[llvm-commits] [patch] Use .loc in codegen

That is the idea :-)

An initial run found problems with files that use "#line". The
attached patch fixes that. Results using
7850396a466baacc66a0bea032a62e3292d1f45c from
git://sourceware.org/git/gdb.git and llvm/clang 119577.

gcc 4.4.3-4ubuntu5:
# of expected passes            16500
# of unexpected failures        21
# of expected failures          90
# of untested testcases         9
# of unsupported tests          74

Without this patch:

# of expected passes            14155
# of unexpected failures        1125
# of unexpected successes       4
# of expected failures          58
# of untested testcases         50
# of unresolved testcases       8
# of unsupported tests          78

With this patch:

# of expected passes            14161
# of unexpected failures        1119
# of unexpected successes       4
# of expected failures          58
# of untested testcases         50
# of unresolved testcases       8
# of unsupported tests          78

Looks like this patch also gives us more passes :-)

I have also attached the test summaries.
