55ae515f9d 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).

dc86704114 Consider this function:
void foo() { __builtin_unreachable(); }

It will output the following on Darwin X86:

_func1:
Leh_func_begin0:
        pushq %rbp
Ltmp0:
        movq %rsp, %rbp
Ltmp1:
Leh_func_end0:

This prolog adds a new Call Frame Information (CFI) row to the FDE with an
address that is not within the address range of the code it describes -- part is
equal to the end of the function -- and therefore results in an invalid EH
frame. If we emit a nop in this situation, then the CFI row is now within the
address range.

f1e309eb48 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.

5e721d7682 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.

ee9eb411ff on darwin empty functions need to codegen into something of non-zero length,
otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

44e05080f8 Bill's change in r95336 broke empty aggregates embedded
in other types.  fix this by only bumping zero-byte globals
up to a single byte if the *entire global* is zero size,
fixing PR6340.

This also fixes empty arrays etc to be handled correctly,
and only does this on subsection-via-symbols targets (aka
darwin) which is the only place where this matters.

38686bdffd 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 :)

983327b351 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.

Only problem seems to be that the parser finalizes OutStreamer 
at the end of the first inline asm, which isn't what we want.
For example:

$ cat asm.c
int foo(int X) {
 __asm__ ("incl    %0" : "+r" (X));
 return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
	subq	$8, %rsp
	movl	%edi, (%rsp)
	movl	%edi, %eax
	## InlineAsm Start
	incl    %eax
	## InlineAsm End
	movl	%eax, (%rsp)
	movl	%eax, 4(%rsp)
	addq	$8, %rsp
	ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:

representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

345ef343cc DwarfDebug: Allocate DIEValues with a BumpPtrAllocator. Most of them are
POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).

~6% less mallocs and ~1% compile time improvement on clang -O0 -g oggenc.c
