Duraid Madina 0ebb0b1c5c fix stack corruption! Previously, 16-byte whole-FP-register stores were
being treated as needing only 8 bytes (though they were 16 byte aligned.)

This should fix a bunch of tests - anyone have any comments, though?

  - in Target.td , SpillSize and SpillAlignment seem dead - is this what
    Size and Alignment do now?
  - in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
    DeclaredSpillAlignment seem dead.
  - there are a bunch of comments here and there that don't clearly
    distinguish between 'size' and 'spillsize' etc. hmm.

Evan Cheng bec9d720b0 Bug fixes: fpGETRESULT should produces a flag result and X86ISD::FST should
read a flag.

Duraid Madina e995910e64 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.

Chris Lattner e636ba84b5 Silly Sparc is big endian. If we have to load args out of incoming stack slots
that are smaller than an int, make sure to adjust the frame pointer to take
this into consideration.

Chris Lattner e96523474b Don't print a label for the first MBB in a function.
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
