R600/SI: Move SIInsertWaits into AMDGPUPassConfig::addPreSched2()

This pass needs to be run after PrologEpilogInserter, because
that pass may inserter spill code which reads or writes memory.

Make the Verifier more strict about gc.statepoints

The recently added documentation for statepoints claimed that we checked the parameters of the various intrinsics for validity.  This patch adds the code to actually do so.  I also removed a couple of redundant checks for conditions which are checked elsewhere in the Verifier and simplified the logic using the helper functions from Statepoint.h.

Simplify ownership of RegClasses by using list<CodeGenRegisterClass> instead of vector<CodeGenRegisterClass*>

This complicates a few algorithms due to not having random access, but
not by a huge degree I don't think (open to debate/design
discussion/etc).

Strength Verifier checks around the types involved in a statepoint

Add checks that the types in a gc.statepoint sequence match the wrapper callee and that relocating a pointer doesn't change it's type.

Split the set of identified struct types into opaque and non-opaque ones.

The non-opaque part can be structurally uniqued. To keep this to just
a hash lookup, we don't try to unique cyclic types.

Also change the type mapping algorithm to be optimistic about a type
not being recursive and only create a new type when proven to be wrong.
This is not as strong as trying to speculate that we can keep the source
type, but is simpler (no speculation to revert) and more powerfull
than what we had before (we don't copy non-recursive types at least).

I initially wrote this to try to replace the name based type merging.
It is not strong enough to replace it, but is is a useful addition.

With this patch the number of named struct types is a clang lto bootstrap goes
from 49674 to 15986.
