Crash when compiling with non-semantic debuginfo

[arcady-lunarg]

When compiling the shader in the attached file with glslangValidator -gVS --target-env vulkan1.3 3188.frag -o 3188.dbg.spv, glslang crashes with the following assert:

glslangValidator: /home/arcady/glslang/SPIRV/SpvBuilder.cpp:967: spv::Id spv::Builder::makeMemberDebugType(const spv::Id, const spv::Builder::DebugTypeLoc &): Assertion `debugId[memberType] != 0' failed.

Here is a reduced version of the shader that still exhibits the issue.

After #3359 this will no longer crash, but will not generate debug info for the buffer reference struct members. The full fix is awaiting a pending spec change that will allow forward references in extended instruction sets' instructions.

-gVS for some reason can't handle large shaders with a lot of helper functions. It just silently fails with -1073741819 error code. You can take any shader from the @TheForge to reproduce.

@helviett That seems like a separate issue. Could you file a separate issue with a link to a specific shader that reproduces it?
