specifically the emulated `exchanged` field of the returned struct.
It should be true if and only if the `old_value`, i.e. the return value

equals to new value.

I added the forcing of the "loop" attribute to all loops to address FXC
failing on uniformity errors related to gradients in loops. Since then,
Tint now implements UA and it recently became an error, so we no longer
need this hack. As a result, FXC is now better able to cope with loops
that it determines executes 0 times.
Most e2e tests are affected because so many use loops, but 27 tests that
were previously failing are now passing with this change:

Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members. This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.
Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).
