/** Fail SPIR-V parsing
*
* This function logs an error and then bails out of the shader compile using
* longjmp. This being safe relies on two things:
*
* 1) We must guarantee that setjmp is called after allocating the builder
* and setting up b->debug (so that logging works) but before before any
* errors have a chance to occur.
*
* 2) While doing the SPIR-V -> NIR conversion, we need to be careful to
* ensure that all heap allocations happen through ralloc and are parented
* to the builder. This way they will get properly cleaned up on error.
*
* 3) We must ensure that _vtn_fail is never called while a mutex lock or a
* reference to any other resource is held with the exception of ralloc
* objects which are parented to the builder.
*
* So long as these two things continue to hold, we can easily longjmp back to
* spirv_to_nir(), clean up the builder, and return NULL.
