COFF: Emit a COFF symbol table if /debug:dwarf is specified. This effectively reverts r318548 and r318635 while keeping the functionality behind the flag and preserving the bug fix from r318548. Differential Revision: https://reviews.llvm.org/D40264 llvm-svn: 318721

# RUN: yaml2obj < %s > %t.obj

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651

[COFF] Add an LLD specific option -debug:symbtab With this set, we retain the symbol table, but skip the actual debug information. This is meant to be used by the MinGW frontend. Differential Revision: https://reviews.llvm.org/D48745 llvm-svn: 335946

COFF: Layout sections in the same order as link.exe One place where this seems to matter is to make sure the .rsrc section comes after .text. The Win32 UpdateResource() function can change the contents of .rsrc. It will move the sections that come after, but if .text gets moved, the entry point header will not get updated and the executable breaks. This was found by a test in Chromium.

Reland r330223, "COFF: Merge .idata, .didat and .edata into .rdata by default.", which was reverted in r330228. In this reland I removed an unnecessary use of /debug in the test delayimports32.test and used the /pdbaltpath flag in the test pdb-publics-import.test, both of which avoid embedding absolute PDB paths in executables which could affect later RVAs.
