In HS, store_per_vertex_output maps to storeOutput in DXIL. The data
that isn't per-vertex is patch constants.

This *almost* matches what GLSL wants, except for the handling of
large widths. You can see this in the lowering algorithm:
(('bitfield_insert', 'base', 'insert', 'offset', 'bits'),
('bcsel', ('ult', 31, 'bits'), 'insert',
('bfi', ('bfm', 'bits', 'offset'), 'insert', 'base')),
'options->lower_bitfield_insert'),
DXIL's 'bfi' instruction is an inseparable pairing of NIR's 'bfi(bfm(...), ...)',
so we just apply the additional bcsel in the backend.

Note that GL requires input coverage for sample execution mode to
be only the single bit corresponding to the executing sample, so
rearrange things to understand during shader emitting if we're
executing per-sample to emit the right coverage value.

The CI changes are because WARP fails really hard at gather,
with crashes when doing it on a 1x1 or Nx1 texture, and incorrectly
applying swizzling to the result vector instead of the actual texture
accesses.

MakeDouble is pretty straightforward, but SplitDouble is interesting
since it returns a unique 2-element struct.

This is support-code to emit the DirectX Intermediate Language, which is
a dialect of LLVM 3.7 bitcode. Because modern versions of LLVM doesn't
support emitting bitcode for older versions, and we can't rely on an old
LLVM version because we need the OpenCL support from Clang later on, we
instead implement our own LLVM bitcode encoder as part of this work.
See the official DXIL documentation for more details on DXIL:
https://github.com/Microsoft/DirectXShaderCompiler/blob/master/docs/DXIL.rst
The reason this comes as a separate library, is because we're also using
this code as the basis for an OpenCL C compiler, which will follow as a
separate merge-request later.
This is the combination of more than 230 commits from our development
branch, including the work from several authors.
