- Originally from crbug.com/tint/804

- Block 25 is not structually reachable, and not part of the loop,
but branches to 80.

- The continue construct with the continue target 37[%37]
is not structurally post dominated by the back-edge block 64[%64]
- The SPIRV-Tools inliner no longer creates such cases. It splits the
single-block loop and pushes the continue target down.

When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.
A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.
This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.

This function was attempting to pick a higher-precision type by using
the decltype() of FROM + TO. This doesn't work if FROM and TO are both
similar bit-widths, and of a different signness, as the picked type may
not be wide enough to hold both the signed and unsigned representation.
Just use AInt or AFloat (both 64-bit), which are the largest types
supported by WGSL.
