XFAIL this on PPC Linux. This keeps showing up in the buildbot and isn't easy to fix, and I'd like it to stop masking 
real failures.

EXPECT_EQ(expected, actual) .  This will make error messages understandable as
it uses terms such as "expected" and "actual" based on the order of arguments.

Add the beginnings of an implementatation of lazy liveness analysis, based on "Fast Liveness Checking for SSA-form Programs" by Boissinot, et al.

This is still very early, hasn't been tested, and is not yet well documented.  More to come soon.

Revert 73074 and 73099 because Windows doesn't have POSIX
regular expressions.  We will add an OpenBSD implementation
and re-apply ASAP.

immediately casted. At present, this is just a minor code
simplification. In the future, the expansion code may be able
to make better choices if it knows what the desired result
type will be.

PIC16 emits auto variables as globals. When optimizer removes a function entierly by estimating its side effects on globals, those globals(autos) without a function were not being printed by the Asm printer.

Change IndexedModeAction representation.

This changes the IndexedModeAction representation to remove the
limitation on the number of value types in MVT.  This limitation
prevents us from specifying AVX types.

Prior to this change IndexedModActions was represented as follows...

uint64_t IndexedModeActions[2][ISD::LAST_INDEXED_MODE];

the first dimension was used to represent loads, then stores.  This
imposed a limitation of 32 on the number of value types that could be
handled with this method.  The value type was used to shift the two bits
into and out of the approprate bits in the uint64_t.

With this change the array is now represented as ...

uint8_t IndexedModeActions[MVT::LAST_VALUETYPE][2][ISD::LAST_INDEXED_MODE];

Takes more space but removes the limitation on MVT::LAST_VALUETYPE.  The
first dimension is now the value_type for the reference.  The second
dimension is the load [0] vs. store[1].  The third dimension represents
the various modes for load store.  Accesses are now direct, no shifting
or masking.

There are other limitations that need to be removed, so that
MVT::LAST_VALUETYPE can be greater than 32.  This is merely the first
step towards that goal.
