Ethan Nicholas a9c187e5cc Revert "Refactored SPIR-V RelaxedPrecision handling"
This reverts commit 9e476b798f.

Reason for revert: Angry Vulkan bots

Original change's description:
> Refactored SPIR-V RelaxedPrecision handling
>
> The RelaxedPrecision decoration is now handled by nextId(), to make it
> easier to see all spots where a RelaxedPrecision decoration might be
> necessary. The goal of this initial refactor is not to actually fix the
> issues with RelaxedPrecision decorations, but rather to lay the
> groundwork for doing so in followup CLs.
>
> The initial intent of this change was to not affect the SPIR-V at all,
> saving modifications for followups, but there ended up being three kinds
> of changes to the output:
>
> 1. Doing things at nextId() time rather than later means some
> decorations move to an earlier spot in the output. This results in
> diffs, but should not cause any behavioral changes.
> 2. We were incorrectly tagging bools as RelaxedPrecision in some
> situations. By funneling things through fewer code paths, the refactor
> would have caused this to happen in even more situations, and the code
> responsible for the bug was being rewritten in this CL anyway, so it
> seemed worth just fixing the issue as part of this change.
> 3. Funneling things through fewer code paths ended up adding
> (correct) RelaxedPrecision modifiers to binary operations that had
> previously been missing them. It seemed better to just let it happen
> than to try to maintain bug-for-bug compatibility with the previous
> approach.
