e4d87aa2de For PR950:
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

a5546fbd10 Evan implemented the machineinstr improvements.
The rot example works if the type is cast to ubyte.

Move sroa examples together and upgrade them to HEAD syntax.

1628cec4d7 For PR950:
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.
