151b044b75 Only erase virtregs with no uses left. 
Also make sure registers aren't erased twice if the dead def mentions
the register twice.

39edcc75ac Fix PR12858, a crash due to GVN's PRE not fully removing an instruction from the 
leader table.  That's because it wasn't expecting instructions to turn up as
leader for a value number that is not its own, but equality propagation could
create this situation.  One solution is to have the leader table use a WeakVH
but this slows down GVN by about 5%.  Instead just have equality propagation not
add instructions to the leader table, only constants and arguments.  In theory
this might cause GVN to run more (each time it changes something it runs again)
but it doesn't seem to occur enough to cause a slow down.

2a600ff5f4 This patch adds a predicate to existing mips32 and mips64 so that those 
instruction encodings can be excluded during mips16 processing.

This revision fixes the issue raised by Jim Grosbach.

bool hasStandardEncoding() const { return !inMips16Mode(); }

When micromips is added it will be

bool StandardEncoding() const { return !inMips16Mode()&&  !inMicroMipsMode(); }

No additional testing is needed other than to assure that there is no regression
from this patch.

6e9ef9c931 ARM: .end_data_region mismatch in Thumb2. 
32-bit offset jump tables just use real branch instructions and so aren't
marked as data regions. We were still emitting the .end_data_region
marker though, which assert()ed.

c058c41261 Give a small negative bias to giant edge bundles. 
This helps compile time when the greedy register allocator splits live
ranges in giant functions. Without the bias, we would try to grow
regions through the giant edge bundles, usually to find out that the
region became too big and expensive.

If a live range has many uses in blocks near the giant bundle, the small
negative bias doesn't make a big difference, and we still consider
regions including the giant edge bundle.

Giant edge bundles are usually connected to landing pads or indirect
branches.

dadb6e60b9 Clear kill flags on the fly when joining intervals. 
With physreg joining out of the way, it is easy to recognize the
instructions that need their kill flags cleared while testing for
interference.

This allows us to skip the final scan of all instructions for an 11%
speedup of the coalescer pass.

c9e3c75c4d When legalising shifts, do not pre-build a list of operands which

d8782377c7 Emit memcmp directly from the StringMatcherEmitter. 
There should be no difference in the resulting binary, given a sufficiently
smart compiler. However we already had compiler timeouts on the generated
code in Intrinsics.gen, this hopefully makes the lives of slow buildbots a
little easier.
