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.

Optimize selects of i1 in the presence of 'true' and 'false' operands to simple
logic operations.
This fixes rdar://problem/18960150.

This folds the compare emission into the select emission when possible, so we
can directly use the flags and don't have to emit a separate compare.
