Dmitry Vyukov 9eaae3d8f6 tsan: fix code formatting

Saleem Abdulrasool d0d1638f96 builtins: assembly routines are not static 
Storage Class 3 is static storage.  These symbols need to be marked as external
(storage class 2) so that they can be referenced.  Note that this external is
not the same as ELF "external" visibility, which is indicated by DLL Storage
Class (i.e. __declspec(dllexport) or __declspec(dllimport)).

Kostya Serebryany cd60ed53f6 [asan] when reporting an ODR violation, also print the stack traces where the globals have been registered (thus show the name of shared library or exe to which the global belongs). The reports become a bit too verbose but I do not see any *simple* way to make them more compact. This should be especially helpful when the ODR happens because the same .cc file is used twice in the project in differend DSOs

Saleem Abdulrasool 8f2efc3a91 builtins: add it blocks for Thumb-2 
Add the missing IT-blocks for Thumb-2 compilation for code paths exercised by
older ARM CPUs.  This should fix the buildbots.

Saleem Abdulrasool 1b8f1a4430 compiler-rt: prefer thumb over ARM 
When possible, use Thumb or Thumb-2 over ARM instructions.  This is particularly
important for pure-Thumb environments (e.g. Windows on ARM).  Although, it is
possible to conditionalise this for that target specifically, this is available
on most newer ARM CPUs, and the code remains compatible with older CPUs with no
adverse effects.  It therefore feels better to always prefer Thumb when
possible.
