Subject: Implement transform from signed to unsigned compare

Support unsigned comparison in HCompare IR node
Implement instruction simplifier pass
Implement code generation of HCompare node for all
supported CPU targets

Performance gain on RISC-V:

Integer.compareUnsigned: +7.17%
Long.compareUnsigned:    +7.17%

Add test cases to check simplification from HCompare to HCondition

Test: testrunner.py --target --64 --ndebug --optimizing
