121f09fb05 Right, we break strict aliasing requirements. Make sure to disable strict
aliasing in the C compiler.

775cbdd51a Remove the "really gross hacks" that are there to deal with recursive functions.
Now we collect all of the call sites we are interested in inlining, then inline
them.  This entirely avoids issues with trying to inline a call site we got by
inlining another call site.  This also eliminates iterator invalidation issues.

d54c38b2f4 It's setting up the call args right now, but on the callee side, it's
trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

4d0cda4d5c This is a start on handling setcc instructions. As the comment notes, we
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.

48c937e5c9 Fix a minor bug in previous checking
Enable folding of long seteq/setne comparisons into branches and select instructions
Implement unfolded long relational comparisons against a constants a bit more efficiently

Folding comparisons changes code that looks like this:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %EDX, DWORD PTR [%ESP + 8]
        mov %ECX, %EAX
        or %ECX, %EDX
        sete %CL
        test %CL, %CL
        je .LBB2 # PC rel: F

into code that looks like this:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %EDX, DWORD PTR [%ESP + 8]
        mov %ECX, %EAX
        or %ECX, %EDX
        jne .LBB2 # PC rel: F

This speeds up 186.crafty by 6% with llc-ls.
