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.

Try to fold the multiply into the add/sub or logical operations (when
possible).
This is related to rdar://problem/18369687.

Extend the logical ops selection to also support non-native types such as i1,
i8, and i16.
Fixes rdar://problem/18330589.
