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.

Stephen Lin f799e3f944 Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. 
This was done with the following sed invocation to catch label lines demarking function boundaries:
    sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll
which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct.

Eli Friedman 7b27942fe7 Add x86 fast-isel for calls returning first-class aggregates. rdar://9435872. 
This is r131438 with a couple small fixes.

Eli Friedman 7335e8a720 Back out r131444 and r131438; they're breaking nightly tests. I'll look into 
it more tomorrow.

Eli Friedman 9ac944774f Basic fast-isel of extractvalue. Not too helpful on its own, given the IR clang generates for cases like this, but it should become more useful soon.
