[Debuginfo][COFF] Minimal serialization support for precompiled types records This change adds support for the LF_PRECOMP and LF_ENDPRECOMP records required to read/write Microsoft precompiled types .objs. See https://en.wikipedia.org/wiki/Precompiled_header#Microsoft_Visual_C_and_C++ This also adds handling for the .debug$P section, which is actually a .debug$T section in disguise, found only in precompiled .objs. Differential Revision: https://reviews.llvm.org/D45283 llvm-svn: 329613

[llvm-readobj] Change -long-option to --long-option in tests. NFC We use both -long-option and --long-option in tests. Switch to --long-option for consistency. In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf. While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf). llvm-svn: 359649
