Although there is nothing wrong with this patch, the test added here
uncovers a problem in other parts of the code which cause the test to
fail when running under asan. Reverting the patch until I can fix the
underlying issue(s).

90c2794bfc [DebugInfo] MCP: collect and update DBG_VALUEs encountered in local block
MCP currently uses changeDebugValuesDefReg / collectDebugValues to find
debug users of a register, however those functions assume that all
DBG_VALUEs immediately follow the specified instruction, which isn't
necessarily true. This is going to become very often untrue when we turn
off CodeGenPrepare::placeDbgValues.

Instead of calling changeDebugValuesDefReg on an instruction to change its
debug users, in this patch we instead collect DBG_VALUEs of copies as we
iterate over insns, and update the debug users of copies that are made
dead. This isn't a non-functional change, because MCP will now update
DBG_VALUEs that aren't immediately after a copy, but refer to the same
register. I've hijacked the regression test for PR38773 to test for this
new behaviour, an entirely new test seemed overkill.

bcc00e1afb Recommit r368812 "[llvm/Object] - Convert SectionRef::getName() to return Expected<>"
Changes: no changes. A fix for the clang code will be landed right on top.

Original commit message:

SectionRef::getName() returns std::error_code now.
Returning Expected<> instead has multiple benefits.

For example, it forces user to check the error returned.
Also Expected<> may keep a valuable string error message,
what is more useful than having a error code.
(Object\invalid.test was updated to show the new messages printed.)

This patch makes a change for all users to switch to Expected<> version.

Note: in a few places the error returned was ignored before my changes.
In such places I left them ignored. My intention was to convert the interface
used, and not to improve and/or the existent users in this patch.
(Though I think this is good idea for a follow-ups to revisit such places
and either remove consumeError calls or comment each of them to clarify why
it is OK to have them).

a8eef4e5f5 [llvm-size][test] Improve llvm-size testing
This patch significantly improves the llvm-size testing. The changes
made are:

1) Change all tests to use yaml2obj instead of assembly or pre-canned
   inputs.
2) Move the tests out of the X86 directory, since they don't need to be
   there after 1).
3) Increased test coverage.
4) Added comments to explain purpose of tests.

I haven't attempted to add test coverage for all Mach-O related code, as
I am not familiar enough with that file format to be able to.

Summary:
The default expression of a parameter variable should be imported before
the parameter variable object is created. Otherwise the function is created
with an incomplete parameter variable (default argument is nullptr) and in
this intermediary state the expression is imported. This import can have
a reference to the incomplete parameter variable that causes crash.

0e5530abfc [MinGW] Correct handling different forms of a few options

Add tests for single dash forms of -exclude-all-symbols and

Support single-dash forms of -out-implib and -output-def, support
the equals form of --output-def=<file>. (We previously had a test
to explicitly disallow -out-implib, but it turns out that GNU ld
actually does support it just fine, despite also matching the
-o<file> option.)

Disallow the double-dashed --u form, add a test for -u<symbol>.

72ef113d40 [API] Have SBCommandReturnObject::GetOutput/Error return "" instead of nullptr
Summary:
It seems this was an unintended side-effect of D26698. AFAICT, these
functions did return an empty string before that patch, and the patch
contained code which attempted to ensure that, but those efforts were
negated by ConstString::AsCString, which by default returns a nullptr
even for empty strings.

This patch:
- fixes the GetOutput/Error methods to really return empty strings
- adds and explicit test for that
- removes a workaround in lldbtest.py, which was masking this problem
  from our other tests

20644a9540 Remove minimum toolchain soft-error
Summary:
Back in January I changed the minimum toolchain version required to build clang
and LLVM: D57264. Since then we've release LLVM 8, following
[our process](http://llvm.org/docs/DeveloperPolicy.html#toolchain)
it's therefore now a good time to remove the soft-error and officially deprecate
older toolchains. I tried this out last Tursday night to see if any bots
complained, and I saw no complaints. I also manually audited bots and didn't see
any bot that should break, but their toolchain information is unreliable and
some bots are offline.

Once this patch stick we'll move to C++14 as we've
[already agreed](http://lists.llvm.org/pipermail/llvm-dev/2019-January/129452.html).
