llvmpipe: correct the debug information printed with GALLIVM_PERF=nopt

Browse Source 
GALLIVM_PERF_NO_OPT is "belond" to GALLIVM_PERF environment variable,
not GALLIVM_DEBUG. when GALLIVM_PERF=nopt is passed to llvmpipe,
"-sroa -early-cse -simplifycfg -reassociate -constprop -instcombine -gvn"
should not be printed. Those llvm optimation techniques should only be
printed when the default(-O2) optimation is enabled.

$ GALLIVM_PERF=nopt GALLIVM_DEBUG=dumpbc glmark2

Before apply this patch:

  Invoke as "opt -sroa -early-cse -simplifycfg -reassociate -mem2reg -constprop -instcombine -gvn ir_setup_variant_0.bc | llc -O2 [-mcpu=<-mcpu option>] [-mattr=<-mattr option(s)>]"

After apply this patch:

  Invoke as "opt -mem2reg ir_fs304_variant0.bc | llc -O0 [-mcpu=<-mcpu option>] [-mattr=<-mattr option(s)>]"
