Mehdi Amini 26d628d6ce Change the fast-isel-abort option from bool to int to enable "levels"
Summary:
Currently fast-isel-abort will only abort for regular instructions,
and just warn for function calls, terminators, function arguments.
There is already fast-isel-abort-args but nothing for calls and
terminators.

This change turns the fast-isel-abort options into an integer option,
so that multiple levels of strictness can be defined.
This will help no being surprised when the "abort" option indeed does
not abort, and enables the possibility to write test that verifies
that no intrinsics are forgotten by fast-isel.

; FIXME: FastISel currently returns false if it hits code that uses VSX
; registers and with -fast-isel-abort=1 turned on the test case will then fail.
; When fastisel better supports VSX fix up this test case.
