Vasileios Kalintiris 2041b1dd0b [mips][FastISel] Remove hidden mips-fast-isel option. 
Summary:
This hidden option would disable code generation through FastISel by
default. It was removed from the available options and from the
Fast-ISel tests that required it in order to run the tests.

Vasileios Kalintiris 9ec6114860 [mips][FastISel] Fix generated code for IR's select instruction. 
Summary:
Generate correct code for the select instruction by zero-extending
it's boolean/condition operand to GPR-width. This is necessary because
the conditional-move instructions operate on the whole register.
