ObjectFile: Add support for mach-o-style dSYM companion files.

llvm-svn: 139676

Add support for 64-bit object files to Path.

llvm-svn: 129975

Assorted bugfixes in object file handling:

- Adds support for sniffing PE/COFF files on win32 (.exe and .dll)
which are COFF files that have an MS-DOS compatibility stub on
the front of them.

Assorted bugfixes in object file handling:

which are COFF files that have an MS-DOS compatibility stub on

- Fixes a bug in the COFFObjectFile's support for the Microsoft COFF
extension for long symbol names, wherein it was attempting to parse
the leading '/' in an extended symbol name reference as part of the
integer offset.

- Fixes bugs in COFFObjectFile and ELFObjectFile wherein section
and symbol iterators were being returned with uninitialized bytes;
the type DataRefImpl is a union between 2 32-bit words (d.a and d.b)
and a single intptr_t word (p). Only p was being initialized, so in
32-bit builds the result would be iterators with random upper 32-bit
words in their DataRefImpls. This caused random failures when
seeking around in object files.

Delete Path::appendSuffix's return value; it wasn't used anywhere, which
is fine since isn't really necessary to check isValid there anyway.
