The promotion code lost any alignment information, when hoisting loads and
stores out of the loop. This lead to incorrect aligned memory accesses. We now
use the largest alignment we can prove to be correct.

objective C or C++ methods when "self" or "this" were in scope, but had 
invalid locations in a DWARF location list. The lack of a valid value caused
us to use an invalid type value and then we tried to import that invalid 
value and we would crash.

Special detail is added for uninitialized variable analysis as this has
serious performance problems than need to be tracked.

Computing some of this data is expensive, for example walking the CFG to
determine its size. To avoid doing that unless the stats data is going
to be used, we thread a bit into the Sema object to track whether
detailed stats should be collected or not. This bit is used to avoid
computations whereever the computations are likely to be more expensive
than checking the state of the flag. Thus, counters are in some cases
unconditionally updated, but the more expensive (and less frequent)
aggregation steps are skipped.

With this patch, we're able to see that for 'gcc.c':
*** Analysis Based Warnings Stats:
232 functions analyzed (0 w/o CFGs).
  7151 CFG blocks built.
  30 average CFG blocks per function.
  1167 max CFG blocks per function.
163 functions analyzed for uninitialiazed variables
  640 variables analyzed.
  3 average variables per function.
  94 max variables per function.
  96409 block visits.
  591 average block visits per function.
  61546 max block visits per function.

And for the reduced testcase in PR10183:
*** Analysis Based Warnings Stats:
98 functions analyzed (0 w/o CFGs).
  8526 CFG blocks built.
  87 average CFG blocks per function.
  7277 max CFG blocks per function.

  1196 max variables per function.
  2540494 block visits.
  37360 average block visits per function.
  2536495 max block visits per function.

That last number is the somewhat scary one that indicates the problem in
PR10183.

instructions if they are conditional. Also fixed issues where the PC wasn't
getting bit zero stripped for ARM targets when a stack frame was thumb. We
now properly call through the GetOpcodeLoadAddress() functions to make sure
the addresses are properly stripped for any targets that may decorate up
their addresses.

We now don't pass the SIGSTOP signals along. We can revisit this soon, but
currently this was interfering with debugging some older ARM targets that
don't have vCont support in the GDB server.

Bendersky. Specifically: 

* Implemented a new function in libclang: clang_isAttribute

* Fixing TranslationUnit.get_includes to only go through the argument
* buffer when it contains something. This fixed a crash on Windows 

* clang_getFileName returns CXString, not char*. Made appropriate
* fixes in cindex.py - now the relevant tests pass and we can see the
* full locations correctly again (previously there was garbage in
* place of the file name) 
* Exposed clang_getCursorDisplayName to the python bindings
