Subject: finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=caa8870fe09f5526e611434b6bb9f7040c7dfa60;p=oota-llvm.git

finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
and those derived from them.  These are obnoxious because
they were written as: PatLeaf<(bitconvert).  Not having an
argument was foiling adding better type checking for operand
count matching up with what was required (in this case,
bitconvert always requires an operand!)
