Mehdi Amini 945a660cbc 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.

Juergen Ributzka a13cab5b74 [FastIsel][X86] Add support for lowering the first 8 floating-point arguments.
Recommit with fixed argument attribute checking code, which is required to bail
out of all the cases we don't handle yet.

Juergen Ributzka 5ad463f55e Revert "[FastIsel][X86] Add support for lowering the first 8 floating-point arguments."
Reverting it because it breaks several tests.

Chad Rosier a92ef4ba5b [fast-isel] Add X86FastIsel::FastLowerArguments to handle functions with 6 or
fewer scalar integer (i32 or i64) arguments. It completely eliminates the need
for SDISel for trivial functions.

Also, add the new llc -fast-isel-abort-args option, which is similar to
-fast-isel-abort option, but for formal argument lowering.
