Chandler Carruth 402bb38823 Keep track of which source locations are part of a macro argument 
instantiation and improve diagnostics which are stem from macro
arguments to trace the argument itself back through the layers of macro
expansion.

This requires some tricky handling of the source locations, as the
argument appears to be expanded in the opposite direction from the
surrounding macro. This patch provides helper routines that encapsulate
the logic and explain the reasoning behind how we step through macros
during diagnostic printing.

This fixes the rest of the test cases originially in PR9279, and later
split out into PR10214 and PR10215.

There is still some more work we can do here to improve the macro
backtrace, but those will follow as separate patches.

Sean Callanan c6466fc9ab Added checks to the expresssion parser which make 
searching for variables and symbols in the target
more robust.  These checks prevent variables from
being reported as existing if they cannot actually
be evaluated in the current context.

Bill Wendling e367f387af Layout the code for trapping arithmetic so that the overflow case comes after 
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

Akira Hatanaka 2f2d9cbb22 This patch adds a flag in MCAsmInfo that indicates whether dwarf register 
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.

Devang Patel bf8cc60d1b 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".
