David Peixotto 022eb5717f Add hooks for constant folding extensions (#209)
This commit adds placeholder hooks to support constant folding of
extensions.  They are defined in a separate file to make it easy to merge
changes or link in other versions. There should be no upstream changes to
these definitions.

David Peixotto b0fd2d3949 Use opcode class to guide constant folding possibilities (#191)
This change modifies dxil constant folding to use the opcode class when
deciding if a dxil function can be constant folded. We now require a
DxilModule to be available when constant folding dxil functions.

To ensure that the dxil module is available we add a new pass that loads a
dxil module from metadata if it does not exist. We use the new pass in the
dxopt tests for constant folding.

David Peixotto deec58372a Ensure the cached Function->OpCodeClass map is updated (#186)
* Ensure the cached Function->OpCodeClass map is updated

The original goal of this change was to use opcode class for deciding when we
can perform constant folding on a function.

We maintain a mapping from Function* to OpCodeClass inside the OP class.
We wanted to use this map in constant folding to decide if we can constant
fold a function to avoid string comparison on the function names.

However, it turns out that the DxilModule is not always available during
constant folding of dxil calls so we cannot use the map inside of OP. The
change contains a few bug fixes and improvements that came out of trying
to get opcode class working inside constant folding.

  1. Use opcode class in dxil constant folding where possible.
  2. Make sure the opcode cache is refreshed properly.
  3. Remove 64-bit test for bfi.
  4. Add equality comparison for the ShaderModel class.

When switching to use the opcode class for constant folding, we discovered
that our test for 64-bit bfi is invalid. There is no 64-bit overload for
bfi in dxil, so the test we had written was not legal dxil. This change
removes the 64-bit test for bfi constant prop.

David Peixotto ae69cf0a58 Add constant folding for dxil intrinsics (#179)
This commit adds the ability to constant fold dxil intrinsics when
all inputs are constant. We reuse the llvm constant folding
infrastructure and add special cases for calls to dxil intrinsics.

David Peixotto f805233b49 Revert license text in banner comments to original llvm verbage (#33)
Fix #30: Revert license text in banner comments to original llvm verbage

This commit removes the Microsoft-specific copyright in llvm files
and reverts the copyright wording to the original llvm wording.

We used the following method to find the files to change:
1. Find all files in DirectXShaderCompiler that are also in llvm 3.7
2. For those files that have the Microsoft-specific copyright, revert
   it to the original llvm copyright as present in llvm 3.7
3. Revert the copyright in a few files that are not in llvm, but are
   mostly copies of files in llvm:
	lib\Transforms\Scalar\ScalarReplAggregatesHLSL.cpp
	lib\Transforms\Scalar\Reg2MemHLSL.cpp

Leave the Microsoft-specific copyright header in files not present
in stock llvm:
