Teach InlineFunction how to differentiate between multiple-value
return statements and aggregate returns so that it handles both
correctly.

Fix a bunch of 80col violations that arose from the Create API change. Tweak makefile targets to find these better.

Mark calls to llvm.stacksave, llvm.stackrestore as
nounwind. When such calls are inlined into something
else that is invoked, they were getting changed to invokes,
which is badness.

Update the inliner and simplifycfg to handle unwind_to.

llvm-svn: 48086

Update inliner to handle functions that return multiple values.

llvm-svn: 48020

Use while loop.

llvm-svn: 47909

Use cast instead of dyn_cast.
Update test to use multiple return value directly, instead of relying on -sretpromotion.

Create an explicit copy for byval parameters even
when inlining a readonly function.

Do this more neatly.

GC poses hazards to the inliner. Consider:

define void @f() {
...
call i32 @g()
...
}

define void @g() {
...
}

The hazards are:

- @f and @g have GC, but they differ GC. Inlining is invalid. This
may never occur.
- @f has no GC, but @g does. g's GC must be propagated to @f.

The other scenarios are safe:

- @f and @g have the same GC.
- @f and @g have no GC.
- @g has no GC.

This patch adds inliner checks for the former two scenarios.
