LLVM test CodeGen/PowerPC/ctrloops-softfloat.ll tries to check for the absence of sequences of instructions with several CHECK-NOT with one of those directives using a variable defined in another. However CHECK-NOT are checked independently so that is using a variable defined in a pattern that should not occur in the input. This commit changes occurence of the variable for the regex used in its definition, thereby making each CHECK-NOT independent.
