3f202e65e8 Added first bit of support for the dwarf .file directive. This patch collects 
the info from the .file directive and makes file and directory tables that
will eventually be put out as part of the dwarf info in the output file.

5b6b28e897 MC/AsmParser: Stop playing unsafe member function pointer calls, this isn't

 - Downside is we now double dispatch through a stub function, but this isn't

e3a98e546f MC/AsmParser: Add a DarwinAsmParser extension.

8a8d96b89c Revert some unneeded parts of the change in r107886 for the 
.weak_def_can_be_hidden directive.  Chris pointed out that the MCAsmInfo.h/.cpp
chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.

05a4c0b1f2 Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
