93e40b754a Silence Clang's -Wlogical-op-parentheses warning. 
I'm not sure it's really worth expressing this as a range rather than 3 specific equalities, but it doesn't seem fundamentally wrong either.

LowerSwitch::Clusterify : main functinality was replaced with CRSBuilder::optimize, so big part of Clusterify's code was reduced.

2313afcd00 Add a last resort tryInstructionSplit() to RAGreedy. 
Live ranges with a constrained register class may benefit from splitting
around individual uses. It allows the remaining live range to use a
larger register class where it may allocate. This is like spilling to a
different register class.

This is only attempted on constrained register classes.

ce44a7a9ae Correctly deal with identity copies in RegisterCoalescer. 
Now that the coalescer keeps live intervals and machine code in sync at
all times, it needs to deal with identity copies differently.

When merging two virtual registers, all identity copies are removed
right away. This means that other identity copies must come from
somewhere else, and they are going to have a value number.

Deal with such copies by merging the value numbers before erasing the
copy instruction. Otherwise, we leave dangling value numbers in the live
interval.

This fixes PR12927.

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
