Create the new linker type "linker_private_weak_def_auto".
...
It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility. The symbols are removed by the linker from the final linked image
(executable or dynamic library).

Propagate the AlignStack bit in InlineAsm's to the

PrologEpilog code, and use it to determine whether
the asm forces stack alignment or not. gcc consistently
does not do this for GCC-style asms; Apple gcc inconsistently
sometimes does it for asm blocks. There is no
convenient place to put a bit in either the SDNode or
the MachineInstr form, so I've added an extra operand
to each; unlovely, but it does allow for expansion for
more bits, should we need it. PR 5125. Some
existing testcases are affected.
The operand lists of the SDNode and MachineInstr forms
are indexed with awesome mnemonics, like "2"; I may
fix this someday, but not now. I'm not making it any
worse. If anyone is inspired I think you can find all
the right places from this patch.

Implement the "linker_private_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. However, this linkage isn't specific to
Objective-C.
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".
Currently only supported on Darwin platforms.

introduce a new recoverable error handling API to LLVMContext

and use it in one place in inline asm handling stuff. Before
we'd generate this for an invalid modifier letter:
$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl ${0:Z}'
INLINEASM <es:abc incl ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>
Now we generate this:
$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl ${0:Z}'
asm.c:3:12: note: generated from here
__asm__ ("incl %Z0" : "+r" (X));
^
1 error generated.
This is much better but still admittedly not great ("why" is the operand
invalid??), codegen should try harder with its diagnostics :)

Revise debug info machinery to digest nested functions and classes.
...
A certain GDB testsuite case (local.cc) has a function nested inside a
class nested inside another function. GCC presents the innermost
function to llvm-convert first. Heretofore, the debug info mistakenly
placed the inner function at module scope. This patch walks the GCC
context links and instantiates the outer class and function so the
debug info is properly nested. Radar 7426545.

LLVM ERROR: Error parsing inline asm
Only problem seems to be that the parser finalizes OutStreamer

return X;
