[AArch64] Add aarch64_vector_pcs function attribute to Clang This is the Clang patch to complement the following LLVM patches: https://reviews.llvm.org/D51477 https://reviews.llvm.org/D51479 More information describing the vector ABI and procedure call standard can be found here: https://developer.arm.com/products/software-development-tools/\ hpc/arm-compiler-for-hpc/vector-function-abi Patch by Kerry McLaughlin.

Renamed and changed the wording of warn_cconv_ignored As discussed in D64780 the wording of this warning message is being changed to say 'is not supported' instead of 'ignored', and the diag ID itself is being changed to warn_cconv_not_supported. llvm-svn: 366368

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.
