ARM64: Change code emitted by ClinitCheck.
Change the code from MVN+CBNZ to CMP+BLO. The latter is
better optimized in ARM64 CPUs. To avoid increasing code
size, this requires the preceding load to be changed from
LDR to LDRB for a single byte of the 32-bit field.
This shows small but measurable improvement on a few Golem
benchmarks, for example MicroLambda, KotlinAutoReversiBench
and KotlinImgProc-GaussianBlurOpt.
Test: testrunner.py --target --optimizing
