c23197a26f 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").

c25e7581b9 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.

334143d304 I give up on trying to use reader/writer locks for recursive type refinement. Use a recursive mutex instead, which will (in theory) generate more contention, but is really 
a much more natural fit for what's going on during recursive type refinement.

4f0ac58da1 We need to guard reads of the AbstractTypeUsers list, as well as writes to it. While it would be nice to use a R/W lock here, 
we can't, because it HAS to be recursive.

6de29f8d96 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.

a5f54a06b0 Create FunctionType::isValidArgumentType to go along with isValidReturnType. 
Also create isValidElementType for ArrayType, PointerType, StructType and
VectorType.

Make LLParser use them. This closes up some holes like an assertion failure on:

  %x = type {label}

but largely doesn't change any semantics. The only thing we accept now which
we didn't before is vectors of opaque type such as "<4 x opaque>". The opaque
can be resolved to an int or float when linking.
