#4784 [interpreter] Use array bounds check instructions to optimize array load and store bytecodes.
Reviewed-by: aoqi
Contributed and tested by: jiangshaofeng, aoqi
Added Loongson EXT instructions such as gslwle/gslwgt. These instructions can check array bound automatically, throw exceptions when index is out of bound.
These instructions were used to accelerate Java byte-code in the interpreter, such as iaload, iastore.
Added UseBoundCheckInstruction to enable/disable the use of these instructions.
UseBoundCheckInstruction is under development yet:
1. C1/C2 is not supported.
2. Array index not out of bound load & store passed, but array index out of bound load & store would crash.
