### Compilation failed:

error: 1: sk_SecondaryFragColor is not allowed in SPIR-V
1 error
Fix fuzzer-discovered error with sk_SecondaryFragColor in SPIR-V. sk_SecondaryFragColor corresponds to an ES2-only concept (gl_SecondaryFragColorEXT) and does not have any SPIR-V equivalent. Two fixes were needed: - sk_SecondaryFragColor shouldn't be in SPIR-V code at all. Report it as an error when it appears. - We don't stop compilation when this error is reported, so we need to fix up the assertion that the fuzzer initially discovered. Specifically, the fuzzer found that the `sk_SecondaryFragColor` variable never got a SPIR-V ID assigned to it in fVariableMap, so the compiler would assert when assembling an expression containing that variable. Now, we make sure to populate fVariableMap with an (unused) ID in `writeGlobalVar` to avoid this crash.

Fixed a past-the-end error location in SPIR-V output The error was being reported at the position of the var declaration, rather than the position of the reference. And since the declaration was in a module, its position was both incorrect (with respect to the program source) and could be past the end.
