Fixed memory leak

Better JIT support for aliases

Fixed some typos

Closes GH-6373.

[ci skip]

Checj type guards before loading values into CPU registers

Avoid register allocation for ASSIGN into aliased variable (it might be indirectly changed into IS_REFERENCE)

More accurate live range construction

Improve register allocator (give preference to loop variables).

Avoid refcounting when return CV (similar to optimization in VM).

Avoid useless register allocation

Perform trace range propagation

Eliminate dead stores

Eliminate dead load

Eliminate more dead type stores

Eliminate more dead type stores

Eliminate dead type stores

Cleanup (expand and remove simple macros)

Add more hints for register allocator

Optimize out double memory load

Use range inference to eliminate useless comparisons

Fix trace range inference

Copy optimization for (BINARY_OP/ACCIGN + SEND_VAL)

Clenup BINARY_OP + SEND_VAL optimization

Allow tracing JIT cooperate with function JIT.

Tracing JIT support for preloaded scripts
