Primarily done by using SequenceToOffsetTable to reduce the register pressure set tables and then sizing the indices into the tables appropriately. Size a few other table entries based on content as well. Reduces X86RegisterInfo.o by ~9k.

The Mips target adds the signext attribute to signed 32-bit integers in order
to support the N32/N64 correctly. Integers must be promoted to 64-bit bit on
these ABI's.

No functionality changed yet, but this will prevent subsequent patches
from having to handle permutations of various interleaved shuffle
patterns.

The following lldb unit tests fail check-lldb on ubuntu:
TestDataFormatterStdMap.py
TestDataFormatterStdVBool.py
TestDataFormatterStdVector.py
TestDataFormatterSynthVal.py
TestEvents.py
TestInitializerList.py
TestMemoryHistory.py
TestReportData.py
TestValueVarUpdate.py
These unit test failures are for non-core functionality. The intent is to
reduce the check-lldb FAILS to core functionality FAILS and then circle
back later and fix these FAILS at a later date.

has a remarkably unique and efficient lowering.
While we get this some of the time already, we miss a few cases and
there wasn't a principled reason we got it. We should at least test
this. v8 already has tests for this pattern.

This was fixed by making the DWARFFormValue contain the compile unit that it needs so it can decode its form value correctly. Any form value that requires a compile unit will now assert. If any of the assertions that were added are triggered, then code that led to the extraction of the form value without properly setting the compile unit must be fixed immediately.

UnwindLLDB::AddOneMoreFrame to try the fallback unwind plan on
that same stack frame before it tries the fallback unwind plan
on the "next" or callee frame.
In RegisterContextLLDB::TryFallbackUnwindPlan, when we're
trying the fallback unwind plan to see if it is valid, make
sure we change all of the object ivars that might be used in
the process of fetching the CFA & caller's saved pc value
and restore those if we decide not to use the fallback
unwindplan.

(e.g. breakpoints, stop-hooks) before we have any targets - for instance in
your ~/.lldbinit file. These will then get copied over to any new targets
that get created. So far, you can only make stop-hooks.
Breakpoints will have to learn to move themselves from target to target for
us to get them from no-target to new-target.
We should also make a command & SB API way to prime this ur-target.

Fixes the self-host fail. Note that this commit activates dominator
analysis in the combiner by default (like the original commit did).

This s_mov_b32 will write to a virtual register from the M0Reg
class and all the ds instructions now take an extra M0Reg explicit
argument.
This change is necessary to prevent issues with the scheduler
mixing together instructions that expect different values in the m0
registers.

filler such as if delay slot filler have to put NOP instruction into the
delay slot of microMIPS BEQ or BNE instruction which uses the register $0,
then instead of emitting NOP this instruction is replaced by the corresponding
microMIPS compact branch instruction, i.e. BEQZC or BNEZC.

Summary:
TestCases/Linux/heavy_uar_test.cc was failing on my
PowerPC64 box with GCC 4.8.2, because the compiler recognised
a memset-like loop and turned it into a call to memset, which
got intercepted by __asan_memset, which got upset because it was
being called on an address in high shadow memory.
Use break_optimization to stop the compiler from doing this.
