spirv: link: handle bit_enum/value_enum parameters during id remap
Operands of category `bit_enum` and `value_enum` fell into the `else`
branch and only their mask/value word was advanced past, so any id-typed
parameters that follow (e.g. the `%bias` after `Bias` in `ImageOperands`)
were left unremapped and ended up referencing whichever instruction landed
on the same final id by chance.5 files changed, 81 insertions(+), 36 deletions(-)
