Add hooks to FoldingSetTrait to allow specializations to provide
...
implementations of equality comparison and hash computation. This
can be used to optimize node lookup by avoiding creating lots of
temporary ID values just for hashing and comparison purposes.

Add the ability to "intern" FoldingSetNodeID data into a
...
BumpPtrAllocator-allocated region to allow it to be stored in a more
compact form and to avoid the need for a non-trivial destructor call.
Use this new mechanism in ScalarEvolution instead of
FastFoldingSetNode to avoid leaking memory in the case where a
FoldingSetNodeID uses heap storage, and to reduce overall memory
usage.

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").

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.

Do not use host floating point types when emitting

this is a bad thing to do in general.

Added "Profile" method to APFloat for use with FoldingSet.

Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().
Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.
