Duraid Madina cc87402925 fix register corruption! (my god.) r15 is a scratch reg, using that as 
a frame pointer is a pretty doofus thing to do. use r5 instead, and
mark it callee-saved, coz that's what it is!

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.

instead of this:

Evan Cheng 14c53b45f5 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.
