.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*.

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".

MC: Add dyn_cast support to MCSection.

MC/Mach-O: Fix some differences in symbol flag handling.
...
- Don't clear weak reference flag, 'as' was only "trying" to do this, it wasn't
actually succeeding.
- Clear the "lazy bound" bit when we mark something external. This corresponds
roughly to the lazy clearing of the bit that 'as' implements in
symbol_table_lookup.
- The exact meaning of these flags appears pretty loose, since 'as' isn't very
consistent. For now we just try to match 'as', we will clean this up one day
hopefully.
