[AMDGPU] Pass to propagate ABI attributes from kernels to the functions The pass works in two modes: Mode 1: Just set attributes starting from kernels. This can work at the very beginning of opt and llc pipeline, but cannot clone functions because it must be a function pass. Mode 2: Actually clone functions for new attributes. This can only work after all function passes in the opt pipeline because it has to be a module pass. Differential Revision: https://reviews.llvm.org/D63208 llvm-svn: 363586

; RUN: opt -S -mtriple=amdgcn-amd-amdhsa -O1 < %s | FileCheck -check-prefix=OPT %s
[test] Fix tests when run on windows after SVN r369426. NFC. When running tests on windows, invoking "llc -march=<arch>" will implicitly use windows as the target os, making these tests misbehave after this change. Fix the issue by using more specific -mtriple values instead of plain -march in these tests. This should hopefully fix buildbot failures like http://lab.llvm.org:8011/builders/clang-x64-windows-msvc/builds/9816. llvm-svn: 369443
