This is necessary on windows targets, since stdout is in text mode there.

MUL is not anymore directly matched because its a pseudoinstruction.
LogicI class fixed to zero-extend immediates. 

llvm-svn: 52036

Added special isel for ADDE,SUBE and new patterns to match SUBC,ADDC

Add a testcase for functions returning first class aggregrates.

over-shift-right should return -1. So here it should be signed-extended,
when bitwidth larger than 64.

work and how to replace them into individual values. Also, when trying to
replace an aggregrate that is used by load or store with a single (large)
integer, don't crash (but don't replace the aggregrate either).

Also adds a testcase for both structs and arrays.

I misread Optimizer Improvements as Other Improvements for some reason.

function is passed as an argument instead of called. Also do this check a bit
earlier.
