When analyzing function calls with interface parameters, all arguments
related to an interface parameter were assumed to escape via the
function arguments. Now, if an argument is related to a non-escaping
parameter with an interface type, the argument may be stack-allocated.

Using a named bitfield with a width more than 0 means we won't hit
weirdness caused by the bitfield not really needing to exist. Changing

The changes are made in the patch for optimized usage of pcmpne/pcmpeq
instructions. The xor with register to register is replaced with pcmpeq
/pcmpne instructions and for immediate check still the xori will be used.
The purpose of the change is to acheive the aggressive usage of pcmpne
/pcmpeq instructions instead of xor being used for comparison.

The sequence of fint/cond_branch is replaced with fcmp/cond_branch. The
fint instruction takes 6/7 cycles as compared to fcmp instruction which
takes 1 cycles. The conversion from float to int with fint instruction
is not required and can directly compared with fcmp instruction which
takes 1 cycle as compared to 6/7 cycles with fint instruction.
