0eb5dadf65 Tidy up to match coding standards. Remove 'else' after 'return' and moving operators to end of preceding line. No functional change intended.

72f7b0811e A DAGCombine optimization for merging consecutive stores. This optimization is not profitable in many cases
because moden processos can store multiple values in parallel, and preparing the consecutive store requires
some work.  We only handle these cases:

1. Consecutive stores where the values and consecutive loads. For example:
  int a = p->a;
  int b = p->b;
  q->a = a;
  q->b = b;

2. Consecutive stores where the values are constants. Foe example:
  q->a = 4;
  q->b = 5;

c94a38ff17 1. Add load/store words from the stack
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.

83ef63efce Remove <def,read-undef> flags from partial redefinitions.
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.

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".
