and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).

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.

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.

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.

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
