[mips] Make sure there is a chain edge dependency between loads that read
...
formal arguments on the stack and stores created afterwards. We need this to
ensure tail call optimized function calls do not write over the argument area
of the stack before it is read out.

[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.

[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.
