Argyrios Kyrtzidis 366985d5eb Make changes to PCHReader to allow reading a PCH file without having a pre-initialized Preprocessor. 
-Introduce 'PCHReaderListener' which is an abstract interface for getting various information from the PCHReader.
-If PCHReader is constructed without a Preprocessor, it can still load the file and invoke the callbacks of PCHReaderListener.
-If PCHReader is constructed with an initialized Preprocessor, PCHValidator is used as a PCHReaderListener to validate the contents of the PCH file against the given Preprocessor.

Chris Lattner 8dd8a52533 Add a skeleton driver for new machine code level fun. llvm-mc is meant 
to be a test driver of other components in the system, which will develop
over time.

Ted Kremenek f9906843b7 libAnalysis: 
- Remove the 'isFeasible' flag from all uses of 'Assume'.
- Remove the 'Assume' methods from GRStateManager.  Now the only way to
  create a new GRState with an assumption is to use the new 'assume' methods
  in GRState.

Evan Cheng de9e36a74e On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body.

Dan Gohman 8c9ac59455 Generalize LSR's OptimizeSMax to handle unsigned max tests as well 
as signed max tests. Along with r73717, this helps CodeGen avoid
emitting code for a maximum operation for this class of loop.

Dan Gohman 4d3c3cfffd Recognize n != 0 ? n : 1 as umax(n, 1). Previously only ULT/UGT/ULE/UGE 
comparisons were recognized for umax, but instcombine canonicalizes
unsigned comparisons with zero to this simpler form.

Owen Anderson 68f6598c69 Insert a SmartMutex templated class into the class hierarchy, which takes a template parameter specifying whether this mutex 
should become a no-op when not running in multithreaded mode.  Make sys::Mutex a typedef of SmartMutex<false>, to preserve source compatibility.

Dan Gohman a0348809b6 Remove the code from IVUsers that attempted to handle 
casted induction variables in cases where the cast
isn't foldable. It ended up being a pessimization in
many cases. This could be fixed, but it would require
a bunch of complicated code in IVUsers' clients. The
advantages of this approach aren't visible enough to
justify it at this time.

Dan Gohman 56bd02c55c Generalize the zext(trunc(t) & C) instcombine to work even with 
C is not a low-bits mask, and add a similar instcombine for
zext((trunc(t) & C) ^ C).

Zhongxing Xu cea6578078 When casting region, if we do not create an element region, record the cast-to 
type. 

When retrieving the region value, if we are going to create a symbol value, use
the cast-to type if possible.

Chris Lattner e7e659431c Fix a crash that can occur when a #pragma handler eats to the end of the 
line, and when the pragma is at the end of a file.  In this case, the last
token consumed could pop the lexer, invalidating CurPPLexer.  Thanks to
Peter Thoman for pointing it out.
