The specification of gnu-debuglink can be found at:
https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html
The file CRC or the CRC value from the .gnu_debuglink section is now
used to calculate the module UUID as a fallback, to allow verifying that
the debug object does match the executable. Note that if a CodeView
build id exists, it still takes precedence. This works even for MinGW
builds because LLD writes a synthetic CodeView build id which does not
get stripped from the debug object.
The `Minidump/Windows/find-module` test also needs a fix by adding a
CodeView record to the exe to match the one in the minidump, otherwise
it fails due to the new UUID calculated from the file CRC.

These tests fail if you build without the x86 llvm backend.
Either because they use an x86 triple or try to backtrace which
requires some x86 knowledge to see all frames.

Update the "image show-unwind" command output to show if the function
being shown is listed as a user-setting or platform trap handler.
Update the individual UnwindPlan dumps to show whether the unwind plan
is registered as a trap handler.
Extend EmulateMOVRdRm to identify "mov r11, sp" in thumb mode as
setting the frame pointer, if r11 is the frame pointer register.

LLDB has three major testing strategies: unit tests, tests that exercise
the SB API though dotest.py and what we currently call lit tests. The
later is rather confusing as we're now using lit as the driver for all
three types of tests. As most of this grew organically, the directory
structure in the LLDB repository doesn't really make this clear.
The 'lit' tests are part of the root and among these tests there's a
Unit and Suite folder for the unit and dotest-tests. This layout makes
it impossible to run just the lit tests.
This patch changes the directory layout to match the 3 testing
strategies, each with their own directory and their own configuration
file. This means there are now 3 directories under lit with 3
corresponding targets:
- API (check-lldb-api): Test exercising the SB API.
- Shell (check-lldb-shell): Test exercising command line utilities.
- Unit (check-lldb-unit): Unit tests.
Finally, there's still the `check-lldb` target that runs all three test
suites.
Finally, this also renames the lit folder to `test` to match the LLVM
repository layout.
