Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Owen Anderson 53a52215b5 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.

Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE.
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Nick Lewycky a21d3daadc Remove the vicmp and vfcmp instructions. Because we never had a release with
these instructions, no autoupgrade or backwards compatibility support is
provided.

Owen Anderson 0d2de8c35e 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.

Owen Anderson b07dd959a4 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.

Dan Gohman 7ccc52f131 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.

Dan Gohman a5b9645c4b 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:

Dan Gohman 79975d5ffb Apply a patch by Micah Villmow to fix AsmParser to accept vector
shift constant expressions, and add support for folding vector
shift constant expressions. This fixes PR3802.

Dale Johannesen b5721632ee Make special cases (0 inf nan) work for frem.
Besides APFloat, this involved removing code
from two places that thought they knew the
result of frem(0., x) but were wrong.

Chris Lattner dd8ef1bf30 div/rem by zero and div/rem overflow are both undefined according to
langref.  Constant fold them to undef instead of trying to preserve
the trap.  This fixes PR3354.

Nick Lewycky f023db6444 Don't crash when trying to constant fold a vector with some elements that can't
be folded. Instead, fail to fold the entire vector.

We could also return a vector with some elements folded and some not. If anyone
thinks that's a better approach, please speak up!

Chris Lattner d137a08b0d Fix three bugs:
1) evaluate [v]fcmp true/false with undefs to true or false instead
   of undef.
2) fix vector comparisons with undef to return a vector result instead 
   of i1
3) fix vector comparisons with evaluatable results to return vector
   true/false instead of i1 true/false (PR2529)
