b99fdee325 reapply my fix for PR8961 with a tweak to properly handle
multi-instruction sequences like calls.  Many thanks to Jakob for
finding a testcase.

d357e88740 revert my fastisel patch again which apparently still gives the
llvm-gcc-i386-linux-selfhost buildbot heartburn...

d754041493 fix PR8961 - a fast isel miscompilation where we'd insert a new instruction
after sext's generated for addressing that got folded.  Previously we compiled
test5 into:

_test5:                                 ## @test5
## BB#0:
        movq    -8(%rsp), %rax          ## 8-byte Reload
        movq    (%rdi,%rax), %rdi
        addq    %rdx, %rdi
        movslq  %esi, %rax
        movq    %rax, -8(%rsp)          ## 8-byte Spill
        movq    %rdi, %rax
        ret

which is insane and wrong.  Now we produce:

_test5:                                 ## @test5
## BB#0:
	movslq	%esi, %rax
	movq	(%rdi,%rax), %rax
	addq	%rdx, %rax
	ret

e667e01723 Use the source-order scheduler instead of the "fast" scheduler at -O0,
because it's more likely to keep debug line information in its original
order.

Debug info intrinsics win for now.

f423a69839 Add X86FastISel support for return statements. This entails refactoring
a bunch of stuff, to allow the target-independent calling convention
logic to be employed.
