21a9a98b77 [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.

6c7ccaa3fd Fix PR11985 
- BlockAddress has no support of BA + offset form and there is no way to
  propagate that offset into machine operand;
- Add BA + offset support and a new interface 'getTargetBlockAddress' to
  simplify target block address forming;
- All targets are modified to use new interface and X86 backend is enhanced to
  support BA + offset addressing.
