cf2c39dc30 Factor some of the constants+context related code out into a separate header, to make LLVMContextImpl.h 
not hideous.  Also, fix some MSVC compile errors.

393d8b0a0c Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp. 
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

these instructions, no autoupgrade or backwards compatibility support is
provided.

733fa621f6 Revert r73790, and replace it with a significantly less ugly solution. Rather than trying to make the global reader-writer lock work, 
create separate recursive mutexes for each value map.  The recursive-ness fixes the double-acquiring issue, which having one per ValueMap
lets us continue to maintain some concurrency.

295610c408 Fix a serious bug that would cause deadlock during abstract type refinement. The constant creation 
gets involved, and we end up trying to recursively acquire a writer lock.  The fix for this is slightly horrible,
and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and
unlocked versions of most of the code.

2e737ac21f Support vector casts in more places, fixing a variety of assertion 
failures.

To support this, add some utility functions to Type to help support
vector/scalar-independent code. Change ConstantInt::get and
ConstantFP::get to support vector types, and add an overload to
ConstantInt::get that uses a static IntegerType type, for
convenience.

Introduce a new getConstant method for ScalarEvolution, to simplify
common use cases.

5f6f8101d5 Split the Add, Sub, and Mul instruction opcodes into separate 
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

316352b541 Add a getAlignOf helper for getting the ABI alignment of a 
type as a target independent constant expression.  I confess
that I didn't check that this method works as intended (though
I did test the equivalent hand-written IR a little).  But what
could possibly go wrong!

Constant* in preperation of a future change to support holding non-Constants
in an MDNode.
