Optimizer: crash when overflowing

[jeroenbakker-atmind]

Not sure this is related to #5753.
Up stream report: https://projects.blender.org/blender/blender/issues/144614

Optimizing 48744-0x000001d18b9e86a0-0x81098.dmp crashes. This is related to the number of object ids it requires during optimization.

spirv-opt.exe 48744-0x000001d18b9e86a0-0x81098.dmp -O -o opt.spv 

To fix this the next commands are needed

spirv-opt.exe 48744-0x000001d18b9e86a0-0x81098.dmp --max-id-bound=99999999 -O -o bad.spv --compact-ids

However as we use shaderc as a frontend we don't have access to these parameters.

I would expect that the optimizer would not crash but would be able to normally exit. This way shaderc could be able to report this and Blender would be able to replace the shader with a default.

We will do two fixes for this:

1. Improve the error handling in spirv-opt. There will be a number of PRs to get this done.
2. We will add an option to shaderc to increase the max id bound.
