Teach the cost model about the optimization in r169904: Truncation of induction variables costs the same as scalar trunc.

This still isn't quite right, but it fixes a crash.

I factored out findCommonParent because we need it on the result of 
getImmediateExpansionRange: for a function macro, the beginning
and end of an expansion range can come out of different
macros/macro arguments, which means the resulting range is a complete
mess to handle consistently.

I also made some changes to how findCommonParent works; it works somewhat
better in some cases, and somewhat worse in others, but I think overall
it's a better balance.  I'm coming to the conclusion that mapDiagnosticRanges
isn't using the right algorithm, though: chasing the caret is fundamentally
more complicated than any algorithm which only considers one FileID for the
caret can handle because each SourceLocation doesn't really have a single parent.
We need to follow the same path of choosing expansion locations and spelling
locations which the caret used to come up with the correct range
in the general case.

Fixes <rdar://problem/12847524>.

I don't think this will be visible just yet on <clang.llvm.org/docs/>
since I don't think that the necessary server-side setup has taken
place.

Don't shoot me over the theme. I don't want to duplicate LLVM's theme
into the clang repo at the moment, so I just used one of Sphinx's
default themes.

also changed MCContext to a single reset only method for simplicity as requested on the list

has inconsistent ownership with the backing ivar, point the error location to the
ivar.

Pointing to the ivar (instead of the @synthesize) is better since this is where a fix is needed.
Also provide the location of @synthesize via a note.

This also fixes the problem where an auto-synthesized property would emit an error without
any location.

unexpected, so we can't rely on the AsmParsers HadError variable directly.

YAMLIO: Remove all of the template instantiation hacks, I don't see why they're necessary and it breaks linking of the unit tests.

Also comes with a clang-format run on the cpp file, it had major style violations.

My variadics patch, r169588, changed these calls to typically be
bitcasts rather than calls to a supposedly variadic function.
This totally subverted a hack where we intentionally dropped
excess arguments from such calls in order to appease the inliner
and a "warning" from the optimizer.  This patch extends the hack
to also work with bitcasts, as well as teaching it to rewrite
invokes.

Added a "step-in-target" flag to "thread step-in" so if you have something like:

Process 28464 stopped
* thread #1: tid = 0x1c03, function: main , stop reason = breakpoint 1.1
    frame #0: 0x0000000100000e08 a.out`main at main.c:62
   61         
-> 62         int A6 = complex (a(4), b(5), c(6)); // Stop here to step targetting b and hitting breakpoint.
   63             

and you want to get into "complex" skipping a, b and c, you can do:

(lldb) step -t complex
Process 28464 stopped
* thread #1: tid = 0x1c03, function: complex , stop reason = step in
    frame #0: 0x0000000100000d0d a.out`complex at main.c:44
   41     
   42     int complex (int first, int second, int third)
   43     {
-> 44         return first + second + third;  // Step in targetting complex should stop here
   45     }
   46         
   47     int main (int argc, char const *argv[])
