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.

earlier.

Fix a memcpy lowering bug. Even though the memcpy alignment is smaller than the desired alignment, the frame destination alignment may still be larger than the desired alignment. Don't change its alignment to something smaller.

Add CallSite::hasArgument to allow for seeing if a call passes a certain value as an argument quickly.

llvm-svn: 51946

Add a Name parameter to two of the init methods of GetElementPointer to make the name setting more consistent.

Add a Name argment to two init methods in these classes as well to make things
a bit more consistent.
