[DWARFv5] CodeGen support for MD5 file checksums Pass MD5 checksums through from IR to assembly/object files. After this, getting Clang to compute the MD5 should be the last step to supporting MD5 in the DWARF v5 line table header. Differential Revision: https://reviews.llvm.org/D41926 llvm-svn: 322391

; MD5 checksums provided by IR should be passed through to asm.
; They'll be emitted to an object file only for DWARF 5 or later.

; OBJ-4: Dir Mod Time File Len File Name
[DWARF] Regularize dumping strings from line tables. The major visible difference here is that in line-table dumps, directory and file names are wrapped in double-quotes; previously, directory names got single quotes and file names were not quoted at all. The improvement in this patch is that when a DWARF v5 line table header has indirect strings, in a verbose dump these will all have their section[offset] printed as well as the name itself. This matches the format used for dumping strings in the .debug_info section. Differential Revision: https://reviews.llvm.org/D42802 llvm-svn: 324270

[DWARFv5] Fix dumper to show the file table starts at index 0. Emitting the correct (root of compilation) file at index 0 will be posted for review later; I wanted to get this minor change out of the way first. llvm-svn: 324669
