6b4f386826 instead of having all conversions be handled by one case value, and then have 
subcases inside, break things out earlier.

02e0c80ecb 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it sees is out of date.

30e43e3126 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.

b125feb99f 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.

to llc when debugging. Also allow other passes to be run from llc.
