* This is a reattempted commit due to a previous builtbot failure
- Now using a env var to determine whether to run the test, as
someone might have built liblldbIntelFeatures.so without intelPT
support, which would make this test fail.
Summary:
Depends on D76872.
There was no test for the Intel PT support on LLDB, so I'm creating one, which
will help making progress on solid grounds.
The test is skipped if the Intel PT plugin library is not built.

Summary:
The DAP specifies the following for the SetBreakpoints request:
The breakpoints returned are in the same order as the elements of the 'breakpoints' arguments
This was not followed, as lldb-vscode was returning the breakpoints in a different order, because they were first stored into a map, and then traversed. Of course, maps normally don't preserve ordering.
See this log I captured:
-->
{"command":"setBreakpoints",
"arguments":{
"source":{
"name":"main.cpp",
"path":"/Users/wallace/fbsource/xplat/sand/test-projects/buck-cpp/main.cpp"
},
"lines":[6,10,11],
"breakpoints":[{"line":6},{"line":10},{"line":11}],
"sourceModified":false
},
"type":"request",
"seq":3
}
<--
{"body":{
"breakpoints":[
{"id":1, "line":11,"source":{"name":"main.cpp","path":"xplat/sand/test-projects/buck-cpp/main.cpp"},"verified":true},
{"id":2,"line":6,"source":{"name":"main.cpp","path":"xplat/sand/test-projects/buck-cpp/main.cpp"},"verified":true},
{"id":3,"line":10,"source":{"name":"main.cpp","path":"xplat/sand/test-projects/buck-cpp/main.cpp"},"verified":true}]},
"command":"setBreakpoints",
"request_seq":3,
"seq":0,
"success":true,
"type":"response"
}
As you can see, the order was not respected. This was causing the IDE not to be able to disable/enable breakpoints by clicking on them in the breakpoint view in the lower corner of the Debug tab.
This diff fixes the ordering problem. The traversal + querying was done very fast in O(nlogn) time. I'm keeping the same complexity.
I also updated a couple of tests to account for the ordering.

Summary:
If no custom launching is used, lldb-vscode launches a program with an empty environment by default. In some scenarios, the user might want to simply use the same environment as the IDE to have a set of working environment variables (e.g. PATH wouldn't be empty). In fact, most DAPs in VSCode have this behavior by default. In other cases the user definitely needs to set their custom environment, which is already supported. To make the first case easier for the user (e.g. not having to copy the PATH to the launch.json every time they want to debug simple programs that rely on PATH), a new option is now offered. inheritEnvironment will launch the program copying its own environment, and it's just a boolean flag.

Summary:
On Linux, when executing lldb-vscode on a remote machine, lldb-vscode doesn't die after the debug session ends. It keeps trying to read JSON input to no avail.
This diff indicates lldb-vscode to stop reading after a termination event has been processed.

This patch removes skipIf decorator from instruction counting tests.
We now use inline intruction in testing inferior to make sure that
number of instructions stays fixed. This was tested on aarch64 linux.
We have a test which checks that instruction-step really steps one
instruction, but the way it checks this makes it very susceptible to
codegen changes. This rewrites the test inferior to use inline assembly,
which guarantees a known sequence of instructions that the test can
check. This does mean we have to write separate assembly for each
architecture, but that is no better than having architecture-specific
assertions, which the test was already starting to accumulate.
This patch makes sure that LLDB AArch64/Linux testsuite skips
single_step_only_steps_one_instruction* tests. There is no possible
gaurantee for this test to pass and there already exists a bug report
against this bug.
Some tests set settings and don't clean them up, this leads to side effects in other tests.
The patch removes a global debugger instance with a per-test debugger to avoid such effects.
From what I see, lldb.DBG was needed to determine the platform before a test is run,
lldb.selected_platform is used for this purpose now. Though, this required adding a new function
to the SBPlatform interface.

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:
lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
lldb-shell :: Reproducer/TestGDBRemoteRepro.test
lldb-shell :: Reproducer/TestMultipleTargets.test

lldb-shell :: ExecControl/StopHook/stop-hook-threads.test

Summary: The VS Code DAP expects on response for each breakpoint that was requested. If we responsd with multiple entries for one breakpoint the VS Code UI gets out of date. Currently the VS code DAP doesn't handle one breakpoint with multiple locations. If this ever gets fixed we can modify our code.

Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.
This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys
def sanitize_line(line):
if line.strip().startswith("self.assertTrue(") and " == " in line:
line = line.replace("self.assertTrue(", "self.assertEquals(")
line = line.replace(" == ", ", ", 1)
if line.strip().startswith("self.assertTrue(") and " != " in line:
line = line.replace("self.assertTrue(", "self.assertNotEqual(")
line = line.replace(" != ", ", ", 1)
return line
for a in sys.argv[1:]:
with open(a, "r") as f:
lines = f.readlines()
with open(a, "w") as f:
for line in lines:
f.write(sanitize_line(line))
```

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
