[builtins][test] Delete unneeded file headers We don't add file headers to tests. The comments are useless as well - their purpose can be easily inferred from the filenames.

[profile][test] Fix Profile-* :: instrprof-merge.c etc. on SPARC While working on https://reviews.llvm.org/D40900 (which effectively is about enabling compiler-rt on sparc these days), I came across two failing profile testcases: Profile-sparc :: instrprof-merge-match.test Profile-sparc :: instrprof-merge.c Profile-sparcv9 :: instrprof-merge-match.test Profile-sparcv9 :: instrprof-merge.c All of them crashed with a SIGBUS in __llvm_profile_merge_from_buffer: Thread 2 received signal SIGSEGV, Segmentation fault. [Switching to Thread 1 (LWP 1)] 0x00012368 in __llvm_profile_merge_from_buffer ( ProfileData=0x2384c <main.Buffer> "\377lprofR\201", ProfileSize=360) at /vol/llvm/src/llvm/local/projects/compiler-rt/lib/profile/InstrProfilingMerge.c:95 95 SrcDataEnd = SrcDataStart + Header->DataSize; where Header is insufficiently aligned for a strict-alignment target like SPARC. Fixed by forcing the alignment to uint64_t, the members of struct __llvm_profile_header, in the callers. Tested on sparcv9-sun-solaris2.11. https://reviews.llvm.org/D64498 llvm-svn: 365805
