a292fa3d1e Recompute register class and hint for registers created during spilling. 
The spill weight is not recomputed for an unspillable register - it stays infinite.

- Also emit a list of packages and groups sorted by name
  - Avoid iterating over DenseSet so that the output of the arrays is deterministic.

4fe82e640f Fixed the build of Clang's unit tests on MinGW. Also removed some 
unnecesary conditionals and introduced a new convenience function.

The problem was that the list of libraries for Clang's unit tests was
<clang libraries> <system libraries> <llvm libraries>. As the llvm
libraries references symbols defined on the system libraries, those
were reported as undefined.

a28b1da096 DSE: Remove an early exit optimization that depended on the ordering of a SmallPtrSet. 
Fixes PR9569 and will hopefully make selfhost on ASLR-enabled systems more deterministic.

4676323ac8 Run dead code elimination immediately after rematerialization. 
This may eliminate some uses of the spilled registers, and we don't want to
insert reloads for that.

c209e050dd Properly enable rematerialization when spilling after live range splitting. 
The instruction to be rematerialized may not be the one defining the register
that is being spilled. The traceSiblingValue() function sees through sibling
copies to find the remat candidate.

5bcaef9cc9 Optimizing (zext A + zext B) * C, to (VMULL A, C) + (VMULL B, C) during 
isel lowering to fold the zero-extend's and take advantage of no-stall
back to back vmul + vmla:
 vmull q0, d4, d6
 vmlal q0, d5, d6
is faster than
 vaddl q0, d4, d5
 vmovl q1, d6                                                                                                                                                                             
 vmul  q0, q0, q1

This allows us to vmull + vmlal for:
    f = vmull_u8(   vget_high_u8(s), c);
    f = vmlal_u8(f, vget_low_u8(s),  c);

cb8447ad52 In some cases, the "fail BB dominator" may be null after the BB was split (and

8c488cb152 Again adding a C API to the disassembler for use by such tools as Darwin's 
otool(1), this time with the needed fix for case sensitive file systems :) .
This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.

9b9cae35db Drop interference reassignment in favor of eviction. 
The reassignment phase was able to move interference with a higher spill weight,
but it didn't happen very often and it was fairly expensive.

The existing interference eviction picks up the slack.
