[CodeGen] Convert tests to opaque pointers (NFC) Conversion performed using the script at: https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34 These are only tests where no manual fixup was required.

-fms-extensions: Recognize _alloca as an alias for the alloca builtin Differential Revision: http://llvm-reviews.chandlerc.com/D1989 llvm-svn: 194617

Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940

[CodeGen] Provide an appropriate alignment for dynamic allocas GCC documents __builtin_alloca as aligning the storage to at least __BIGGEST_ALIGNMENT__. MSVC documents essentially the same for the x64 ABI: https://msdn.microsoft.com/en-us/library/x9sx5da1.aspx The 32-bit ABI follows the same rule: it emits a call to _alloca_probe_16 Differential Revision: https://reviews.llvm.org/D24378 llvm-svn: 285316

Add support for __builtin_alloca_with_align __builtin_alloca always uses __BIGGEST_ALIGNMENT__ for the alignment of the allocation. __builtin_alloca_with_align allows the programmer to specify the alignment of the allocation. This fixes PR30658. llvm-svn: 285544
