Fixed incorrect invariant guard motion

Create TSSA loops for recursive call/return traces and move invariant type guards out of loops.

Fixed memory leak in Zend/tests/bug78999.phpt

Fixed tracing JIT support for aliasses (Zend/tests/bug75420.13.phpt and ext/standard/tests/streams/bug60106.phpt)

Fixed support for named parameters (Zend/tests/named_params/references.phpt)

Fixed tracing JIT for tests/classes/unset_properties.phpt

Fixed memory leak

Better JIT support for aliases

Fixed some typos

Closes GH-6373.

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
