Saleem Abdulrasool 3681929e11 IAS: correct debug line info for asm macros
Correct the line information generation for preprocessed assembly.  Although we
tracked the source information for the macro instantiation, we failed to account
for the fact that we were instantiating a macro, which is populated into a new
buffer and that the line information would be relative to the definition rather
than the actual instantiation location.  This could cause the line number
associated with the statement to be very high due to wrapping of the difference
calculated for the preprocessor line information emitted into the stream.
Properly calculate the line for the macro instantiation, referencing the line
where the macro is actually used as GCC/gas do.

The test case uses x86, though the same problem exists on any other target using
the LLVM IAS.
