This only rejects mismatches between target specific calling convention
and C/LLVM specific calling convention.
There are too many fastcc/C, coldcc/cc42 mismatches in the testsuite, these are
not reject by the verifier.

type as a target independent constant expression. I confess
that I didn't check that this method works as intended (though
I did test the equivalent hand-written IR a little). But what
could possibly go wrong!

since inttoptr and ptrtoint always use zero-extension when the destination
is larger than the source.

function with no uses cannot be removed unless it is
also marked nounwind.

The real fix for this whole mess is to require the operand of the
alias to be a *GlobalValue* (not a general constant, including
constant exprs) but allow the operand and the alias type to be
unrelated.

restriction.

which are effectively smart pointers to Value*'s. They are both very light
weight and simple, and react to values being destroyed or being RAUW'd.
WeakVN does a best effort to follow a value around, including through RAUW
operations and will get nulled out of the value is destroyed. This is useful
for the eventual "metadata that references a value" work, because it is a
reference to a value that does not show up on its use_* list.
AssertingVH is a pointer that compiles down to a dumb raw pointer when
assertions are disabled. When enabled, it emits an assertion if the
pointed-to value is destroyed while it is still being referenced. This
is very useful for Maps and other things, and should have caught the recent
bugs in CallGraph and Reassociate, for example.

same as a normal i80 {low64, high16} rather
than its own {high64, low16}. A depressing number
of places know about this; I think I got them all.
Bitcode readers and writers convert back to the old
form to avoid breaking compatibility.

unneeded bitcast is requested. This is common for frontends who just unconditionally
cast even if the target is often the right type already. THis prevents going into
getFoldedCast which switches on the opcode and does a bunch of other stuff before
doing the same opzn.
