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.

ARM FastISel integer sext/zext improvements My recent ARM FastISel patch exposed this bug: http://llvm.org/bugs/show_bug.cgi?id=16178 The root cause is that it can't select integer sext/zext pre-ARMv6 and asserts out. The current integer sext/zext code doesn't handle other cases gracefully either, so this patch makes it handle all sext and zext from i1/i8/i16 to i8/i16/i32, with and without ARMv6, both in Thumb and ARM mode. This should fix the bug as well as make FastISel faster because it bails to SelectionDAG less often. See fastisel-ext.patch for this. fastisel-ext-tests.patch changes current tests to always use reg-imm AND for 8-bit zext instead of UXTB. This simplifies code since it is supported on ARMv4t and later, and at least on A15 both should perform exactly the same (both have exec 1 uop 1, type I). 2013-05-31-char-shift-crash.ll is a bitcode version of the above bug 16178 repro. fast-isel-ext.ll tests all sext/zext combinations that ARM FastISel should now handle. Note that my ARM FastISel enabling patch was reverted due to a separate failure when dealing with MCJIT, I'll fix this second failure and then turn FastISel on again for non-iOS ARM targets. I've tested "make check-all" on my x86 box, and "lnt test-suite" on A15 hardware. llvm-svn: 183551
