[mips][msa/dsp] Only do DSP combines if DSP is enabled. Fixes a crash (null pointer dereferenced) when MSA is enabled. llvm-svn: 195343

; RUN: llc -march=mips -mattr=+msa,+fp64 < %s

; This test originally failed for MSA after dereferencing a null this pointer.
; It should at least successfully build.
