Chris Lattner f59b2daddb Allow targets to have custom expanders for FP_TO_*INT conversions where 
both the src and dest values are legal

Chris Lattner bc85c32c73 Implement a FIXME: move a bunch of cruft for handling FP_TO_*INT operations 
that the X86 does not support to the legalizer.  This allows it to be better
optimized, etc, and will help with SSE support.

Chris Lattner 67756e2e22 Use a custom expander to compile this: 
long %test4(double %X) {
        %tmp.1 = cast double %X to long         ; <long> [#uses=1]
        ret long %tmp.1
}

to this:

_test4:
        sub %ESP, 12
        fld QWORD PTR [%ESP + 16]
        fistp QWORD PTR [%ESP]
        mov %EDX, DWORD PTR [%ESP + 4]
        mov %EAX, DWORD PTR [%ESP]
        add %ESP, 12
        ret

instead of this:

_test4:
        sub %ESP, 28
        fld QWORD PTR [%ESP + 32]
        fstp QWORD PTR [%ESP]
        call ___fixdfdi
        add %ESP, 28
        ret

subcases inside, break things out earlier.

Andrew Lenharth b57b0baac0 get lazy JITing working. Some of shootout runs now

Andrew Lenharth 3444cf5128 Like constants, globals on some platforms are GOT relative. This means they have to be allocated 
near the GOT, which new doesn't do.  So break out the allocate into a new function.

Also move GOT index handling into JITResolver.  This lets it update the mapping when a Lazy
function is JITed.  It doesn't managed the table, just the mapping.  Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes.  The relocation resolve process updates any GOT entry
it sees is out of date.

Reid Spencer 87c5a8a48a Run the verifier pass after all the other passes rather than before them. 
This catches mistakes in the passes rather than just verifying the bytecode
input to llc.

Nate Begeman c5b6bd9a8e Fold constant adds into loads and stores to frame indices. 
For the following code:
double %ext(int %A.0__, long %A.1__) {
        %A_addr = alloca %typedef.DComplex              ; <%typedef.DComplex*> [#uses=2]
        %tmp.1 = cast %typedef.DComplex* %A_addr to int*                ; <int*> [#uses=1]
        store int %A.0__, int* %tmp.1
        %tmp.2 = getelementptr %typedef.DComplex* %A_addr, int 0, uint 1                ; <double*> [#uses=2]
        %tmp.3 = cast double* %tmp.2 to long*           ; <long*> [#uses=1]
        store long %A.1__, long* %tmp.3
        %tmp.5 = load double* %tmp.2            ; <double> [#uses=1]
        ret double %tmp.5
}

We now generate:
_ext:
.LBB_ext_0:     ;
        stw r3, -12(r1)
        stw r4, -8(r1)
        stw r5, -4(r1)
        lfd f1, -8(r1)
        blr

Instead of:
_ext:
.LBB_ext_0:     ;
        stw r3, -12(r1)
        addi r2, r1, -12
        stw r4, 4(r2)
        stw r5, 8(r2)
        lfd f1, 4(r2)
        blr

This also fires hundreds of times on MultiSource.

Reid Spencer 8e3830dae7 Make the verifier pass run (in debug mode) in llc. This adds a sanity check 
to llc when debugging. Also allow other passes to be run from llc.
