the normal case.

Before, for this:

$ cat t.c
int test(int x) { return x * 2; }

We would get this:

   addl  %edi, %edi
   jno   LBB0_2
## BB#1:                                ## %overflow
   ud2
LBB0_2:                                 ## %nooverflow
   movl    %edi, %eax
   popq    %rbp
   ret

Now we get this:

   addl   %edi, %edi
   jo     LBB0_2
## BB#1:                                ## %nooverflow
   movl                                 %edi, %eax
   popq                                 %rbp
   ret
LBB0_2:                                 ## %overflow
   ud2

numbers should be printed instead of symbolic register names in
MCAsmStreamer::EmitRegisterName. This is necessary because some versions of
GNU assembler won't accept code in which symbolic register names are used in
cfi directives. There is no change in behavior unless the flag is explicitly
set to true by a backend.

If known DebugLocs do not match then two DBG_VALUE machine instructions are not identical. For example,

        DBG_VALUE 3.310000e+02, 0, !"ds"; dbg:sse.stepfft.c:138:18 @[ sse.stepfft.c:32:10 ]
        DBG_VALUE 3.310000e+02, 0, !"ds"; dbg:sse.stepfft.c:138:18 @[ sse.stepfft.c:31:10 ]

These two MIs represent identical value, 3.31...,  for one variable, ds, but they are not identical because the represent two separate instances of inlined variable "ds".

clang_codeCompleteGetContexts(), that provides the client with
information about the context in which code completion has occurred
and what kinds of entities make sense as completions at that
point. Patch by Connor Wakamo!

If we're using the pure non-fragile ABI, then skip some of the contortions required to support the transitional ABI.

Set a flag to tell the runtime when we're compiling in ARC mode and use the pure-nonfragile ABI for both ARC and GC mode.

Fix example: variable is initialized to 10 and then has 11 stored in it, but in the expanded version is initialized to 11.

where we have an immediate need of a retained value.

As an exception, don't do this when the call is made as the immediate
operand of a __bridge retain.  This is more in the way of a workaround
than an actual guarantee, so it's acceptable to be brittle here.
