1a63fa6ec9 Implemented Request #76178 (Class constants are slow: they should be inlined at runtime) 
Run-time cache is used to eliminate recalculation of constant expression in RECV_INIT opcode (only non reference countable values are cached).

b0af9ac733 Avoid live range references in opcodes 
Don't store the live range of the freed variable for FREE_ON_RETURN
frees, instead look it up at runtime. As this is an extremely
unlikely codepath (in particular, it requires a loop variable with
a throwing destructor), saving the runtime lookup of the live range
is not worth the extra complexity this adds everywhere else.
