5cf178f281 Enable the new coalescer algorithm by default. 
The new coalescer is better at merging values into unused vector lanes,
improving NEON code.

657720bc6e Don't dereference begin() on an empty vector. 
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.

465251a7ce Fix a integer overflow in SimplifyCFG's look up table formation logic. 
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).

e2d02349c3 Add missing function CreateFPCast to the TargetFolder. It's there in the other 
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".
