a05a81b10a Use a cheaper test, delaying calling find_leader() until we know that it's necessary. This improves 
the time to optimize Anton's testcase from 21.1s to 17.6s.

2038252c6a 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.

532dc2e1f2 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.

93f81e2822 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.
