Akira Hatanaka 6a124a84dc [mips] Do not tail-call optimize vararg functions or functions with byval 
arguments.

This is rather conservative and should be fixed later to be more aggressive.

Akira Hatanaka 90131ac26c [mips] Add code to do tail call optimization. 
Currently, it is enabled only if option "enable-mips-tail-calls" is given and
all of the callee's arguments are passed in registers.
