Various SPIRV fixes. (#3231)
* Various SPIRV fixes.
- Geometry shader support (WIP).
- Fix texture get dimension and load.
- Fold global GetElement(MakeArray/MakeVector) insts.
- Call spvopt to inline all functions.
- Translate OpImageSubscript.
- Emit struct member names and global variable names.
- Fix lowering of OpBitNot -> OpNot, instead of OpBitReverse.
* Fix test.
* Fix geometry shader.
* Fix geometry shader emit.
* Add atomic Image access test.
* Fix tests.
* don't fail if spirv-opt fails.
* Update comments.
* Fix test.
* Cleanups.
* indentation
