compiler: Analyze escape information of interface parameters.

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.

Improve the test in bitfields.m4

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
int to long long means we won't have trouble with some arch where size

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
