CorrelatedPropagation: BasicBlock::removePredecessor can simplify PHI nodes. If the it's the condition of a SwitchInst, reload it.

2. As part of this, added assembly format FEXT_RI16_SP_explicit_ins and
moved other lines for FEXT_RI16 formats to be in the right place in the code.
3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment.
4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem.

The new coalescer can turn a full virtual register definition into a
partial redef by merging another value into an unused vector lane.

Make sure to clear the <read-undef> flag on such defs.

The new coalescer is better at merging values into unused vector lanes,
improving NEON code.

The fix is obvious and the only test case I have is horrible, so I am
not including it. The problem shows up when self-hosting clang on i386
with -new-coalescer enabled.

If the width is very large it gets truncated from uint64_t to uint32_t when
passed to TD->fitsInLegalInteger. The truncated value can fit in a register.
This manifested in massive memory usage or crashes (PR13946).

folders and not having it here fails to compile if you actually try to use it.

Also, CreatePointerCast was failing to do the part where it does TD-aware
constant folding. Granted there is exactly one case where that it will ever
do anything, but there's no reason to skip it. For reference, that case is a
subtraction between two constant offsets on the same global variable, eg.,
"&A[123] - &A[4].f".

This is a preliminary step towards ELF support; currently ARMFastISel hasn't
been used for ELF object files yet.
