Turning on cxx_nullptr exposed a latent bug in is_function, causing nullptr to wrongly classify as a function.  Fixed.

Fixes valgrind errors in the CellSPU backend.

floating-point comparison, generate a mask of 0s or 1s, and generally
DTRT with NaNs.  Only profitable when the user wants a materialized 0
or 1 at runtime.  rdar://problem/5993888

Don't use stdint.h; including it directly is not allowed from LLVM code because it doesn't exist on MSVC.

constant-expression, and, therefore, an unevaluated operand. Make it
so.

Add TargetRegisterInfo::hasSubClassEq and use it to check for compatible
register classes instead of trying to list all register classes in
X86's getLoadStoreRegOpcode.

This patch is another step in the direction of adding vector select. In this
patch we add a flag to enable a new type legalization decision - to promote
integer elements in vectors. Currently, the rest of the codegen does not support
this kind of legalization.  This flag will be removed when the transition is
complete.

a file was modified since the time the PCH was created.

The parser is not fit to deal with stale PCHs, too many invariants do not hold up. rdar://9530587.

Fix broken test on windows. To get operator new working, we need size_t, for which we need to figure out a way to resolve standard include paths in the test.

For targets with no itinerary (x86) it is a nop by default. For
targets with issue width already expressed in the itinerary (ARM) it
bypasses a scoreboard check but otherwise does not affect the
schedule. It does make the code more consistent and complete and
allows new targets to specify their issue width in an arbitrary way.

- The Swig post-processing scripts are now run.
- edit-swig-python-wrapper-file.py has been modified so it can be run
from the Makefile.
- The issue that prompted me to pass -classic to swig is fixed by this,
so -classic isn't passed anymore.

Python shouldn't complain anymore about a missing method 'FindDebuggerByID'
on the SBDebugger object whenever lldb is run.

landing pad, forward llvm.eh.resume calls to it instead of turning them
invalidly into invokes.

turns out that it could cause an infinite loop in some situations. If this code
is triggered and it converts a cleanup into a catchall, but that cleanup was in
already in a cleanup, then the _Unwind_SjLj_Resume could infinite loop. I.e.,
the code doesn't consume the exception object and passes it on to
_Unwind_SjLj_Resume. But _USjLjR expects it to be consumed (since it's landing
at a catchall instead of a cleanup). So it uses the values that are presently
there, which are the values that tell it to jump to the fake landing pad.

an example implementation of a tool that removes redundant .c_str() calls
is in the example RemoveCStrCalls.cpp.
