Comments: Fix a use-after-free found in libclang when doing code completion. The
loop processing the candidates can cause new declerations to be added to
the context, invalidating lookup_result. To avoid that, make a copy of
the list of declarations to iterate over.

I don't have a way to check in a test case for this as it involves
a giant pile of source code and a generated PCH file used to accelerate
code completion, all of this running under ASan.Properties:

Comments: It appears that glibc 2.13 has the same thread descriptor size as 2.11,
bump up the inflection point to 2.14. If someone can tell me how to
actually figure out value for this, that would be awesome.

Anyways, this takes me to one ASan failure, one LSan failure, and three
TSan failures for 'check-all' on Linux.Properties:

Comments: DebugInfo: Don't emit vbase 'containing types' for context chain limited types

Possible minor reduction in debug info & avoid some cases where creating
a context chain could lead to the type the context chain is being
created for, being created. (this is still possible with template
parameters - tests/fixes/improvements to follow)Properties:

Comments: DebugInfo: Avoid duplicating types that may be created during the process of creating their context

A partner to r188639, this is a somewhat heavy-handed fix to the general
issue, since even after that prior change the issue does still
unavoidably arise with template parameters (see test case).

There are other ways we could consider addressing this (see FIXME).Properties:

Comments: Revert "Revert "DebugInfo: Omit debug info for dynamic classes in TUs that do not have the vtable for that class""

This reverts commit r188600.

r188640/r188639 fixed the root cause of the crash-on-valid that r188600
originally introduced. This now appears to bootstrap debug clang
successfully to the best of my testing.Properties:

Comments: ARM: make sure we keep inline asm operands tied.

When patching inlineasm nodes to use GPRPair for 64-bit values, we
were dropping the information that two operands were tied, which
effectively broke the live-interval of vregs affected.Properties:
