expand it), so ask legalizer to expand i32 UINT_TO_FP.

use proper (82-bit) spills/fills when spilling FP regs, so that
divides don't get broken. this fixes obsequi, smg2000, and probably
a bunch of other stuff (tm)

fixing divides: FP should now be 100%, and integers are fine too
unless you try to div/mod 0 by anything, in which case you will
get some cute number, and not 0, which is bad.

fix division! again!! pattern isel, prepare to die.

that are smaller than an int, make sure to adjust the frame pointer to take
this into consideration.

Compile this:

%_2E_str_8 = external global [75 x sbyte]
implementation   ; Functions:
declare int %printf(sbyte*, ...)
void %test()
        %tmp.101 = call int (sbyte*, ...)* %printf( sbyte* getelementptr ([75 x sbyte]* %_2E_str_8, int 0, int 0) )             ; <int> [#uses=0]
        unreachable
}

to this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        add %l0, %lo(_2E_str_8), %o0
        call printf
        nop

instead of this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        or %g0, %lo(_2E_str_8), %l1   ;; extra instruction
        add %l1, %l0, %o0
        call printf
        nop
