454a8eaee9 Don't drop function/call return attributes like 'nounwind'.

c32be7e6b2 Fix arg promotion to propagate the correct attrs on the calls to
promoted functions.  This is important for varargs calls in 
particular.  Thanks to duncan for providing a great testcase.

f0dd2bb4e6 add a test to ensure that argpromote of one argument doesn't
break the byval attr on some other argument.

a1246ba8ed Teach argpromote to ruthlessly hack small byval structs when it can
get away with it, which exposes opportunities to eliminate the memory
objects entirely.  For example, we now compile byval.ll to:

define internal void @f1(i32 %b.0, i64 %b.1) {
entry:
	%tmp2 = add i32 %b.0, 1		; <i32> [#uses=0]
	ret void
}

define i32 @main() nounwind  {
entry:
	call void @f1( i32 1, i64 2 )
	ret i32 0
}

This seems like it would trigger a lot for code that passes around small
structs (e.g. SDOperand's or _Complex)...

56b310ae49 Make the llvm-runtest function much more amenable by eliminating all the
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.
