Add more 256-bit forms for a bunch of regular AVX instructions
Add 64-bit (GR64) versions of some instructions (which are not

Fix a couple issues with Win64 ABI

1) all registers were spilled as xmm, regardless of actual size
2) win64 abi doesn't do the varargs-size-in-%al thing

Still to look into:

xmm6-15 are marked as clobbered by call instructions on win64 even though they aren't.

Make MDNode::destroy private.
Fix the one thing that used MDNode::destroy, outside of MDNode itself.

Use getDebugLoc and setDebugLoc instead of getDbgMetadata and setDbgMetadata,
avoiding MDNode overhead.

I just fail with SVN today.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108888 91177308-0d34-0410-b5e6-96231b3b80d8

there is no reason to dynamically generate a static header.

Oops.

Convert the internal PassRegistrar class into a new, external PassRegistry class.  No intended functionality change at this point.

hopefully teach cmake to build the .inc file.

cmake too

forgot to add a file

start straightening out libedis's dependencies and make it fit
better in the llvm world.  Among other things, this changes:

1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
   so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
   API depends on it.
4. Various code cleanup changes.

There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.
