Append() method is special: unlike most outputs, it does not copy
some temporary data to a symbol in the entry point epilogue, but
rather uses an emit builtin after each write to the output stream.

This had been handled by remembering the special output symbol for
the stream as it was declared in the shader entry point before
symbol sanitization.  However the prior code was too simple and
only handled cases where the Append() method happened after the
entry point, so that the output symbol had been seen.

This PR adds a patching step so that the Append()s may appear in
any order WRT the entry point.  They are patched in an epilogue,
whereupon it is guaranteed in a well formed shader that we have
seen the appropriate declaration.

Fixes #1217.

Skip outermost array when assigning locations to auto-array interfaces

We want these tests to be independent of whether SPIRV-opt is used.

When assigning a location to an interface whose stage automatically
converts the interfaces to an array, it now strips off the outermost
array from the type before calculating how many locations it consumes.

Fix #944: Convert argument type to match formal parameter type.

Update spirv-opt known-good

Notably, this includes the following:

- Fix exponential performance of DeadInsertElim
- Constant folding of OpVectorTimesScalar
- Add Vector DCE
- Add store-store elimination to LocalSingleBlockElim
- Improve folding of OpVectorTimesScalar and OpPhi
- Fixes handling of kill and unreachable ops in inlining

Fixed install for SPIRV, glslang, and hlsl when building shared libs

Fix issue #1367 - change the I/O remapper to ignore push constants so it does not apply a binding/descriptor set to them.

Update known-good.

Notably, reduces spirv-opt time and adds folding of OpDot and OpFNegate.

Initial way of addressing #1362.

Add AMD float16/int16 SPV extension string when GLSL specifies them

This patch makes  the validator accept *.<stage name>.[g/h]lsl pattern
for file names.

This patch preserves previous behavior (i.e. *.vert/*.frag/etc. in file
names still work).

Fix issue #1350 - set the node type to match the atomic TIntermAggregate node type so that AtomicSMin/Max is not generated with a result type of void.

Changes include:
    Fix SSA rewrite for nested loops.
    Add support for two new extensions:
    - SPV_NV_shader_subgroup_partitioned
    - SPV_EXT_descriptor_indexing
    Legalize OpImageTexelPointer
    Copy propagate arrays
