Have clang_getSpellingLocation() use the same logic as DiagnosticRenderer for plowing through macros.

This fixes a subtle bug reported in <rdar://problem/12584554> where a double-nested
macro could lead to an incorrect fixit location with live issues.

This fix also uncovers a bunch of subtle bugs in our indexer test cases which
are now fixed (mostly around source ranges for attributes).

to format declaration tags for xml comments. Since formatter

tests, only a single tests is formatted using this facility.

PR 14529 was opened because neither Clang or LLVM was expanding
calls to creal* or cimag* into instructions that just load the
respective complex field.  After some discussion, it was not
considered realistic to do this in LLVM because of the platform
specific way complex types are expanded.  Thus a way to solve
this in Clang was pursued.  GCC does a similar expansion.

This patch adds the feature to Clang by making the creal* and
cimag* functions library builtins and modifying the builtin code
generator to look for the new builtin types.

This also requires adding support to -cc1as for passing the detecting
PWD down through LLVM's debug info (which in turn required the LLVM
change in r170371).

The test case is weak (we only test the driver behavior) because there
is currently to infrastructure for running cc1as in the test suite. So
those four lines are untested (much like all other lines in that file),
but we have a test for the same pattern using llvm-mc in the LLVM
repository.

performance heuristic

After inlining a function with more than 13 basic blocks 32 times, we
are not going to inline it anymore. The idea is that inlining large
functions leads to drastic performance implications. Since the function
has already been inlined, we know that we've analyzed it in many
contexts. 

The following metrics are used:
 - Large function is a function with more than 13 basic blocks (we
should switch to another metric, like cyclomatic complexity)
 - We consider that we've inlined a function many times if it's been
inlined 32 times. This number is configurable with -analyzer-config
max-times-inline-large=xx

This heuristic addresses a performance regression introduced with
inlining on one benchmark. The analyzer on this benchmark became 60
times slower with inlining turned on. The heuristic allows us to analyze
it in 24% of the time. The performance improvements on the other
benchmarks I've tested with are much lower - under 10%, which is
expected.
