928144b051 Define non-intrinsic instructions for vector min, max, sqrt, rsqrt, and rcp, 
in addition to the intrinsic forms. Add spill-folding entries for these new
instructions, and for the scalar min and max instrinsic instructions which
were missing. And add some preliminary ISelLowering code for using the new
non-intrinsic vector sqrt instruction, and fneg and fabs.

8d4339f8db Take advantage of the new fast SmallPtrSet assignment operator when propagating AVAIL_OUT sets. 
This reduces the time to optimize Anton's testcase from 31.2s to 21.s!

81cfdc2f19 Change getCopyToParts and getCopyFromParts to always use target-endian 
register ordering, for both physical and virtual registers. Update the PPC
target lowering for calls to expect registers for the call result to
already be in target order.

e48ed4f7a8 Make the assignment operator for SmallPtrSet return a reference, and fix a long-standing bug in the copy 
ctor while I'm at it.

be352027e6 Initialize the IndexedModeActions array with memset before 
updating it with calls to setIndexedLoadAction/setIndexedStoreAction,
which only update a few bits at a time. This avoids ostensible
undefined behavior of operationg on values which may be
trap-representations, and as a practical matter fixes errors from
valgrind, which doesn't track uninitialized memory with bit
granularity.

f695fa9257 Start using a set representation that remembers the set of value numbers represented 
in the set.  For the moment, this results in a slight performance decrease, but
it lays the groundwork for future improvements.
