Clemens Hammacher 327fd140fd [wasm] Revise compile error messages
This CL revises some of our error messages, and removes unneeded parts
(like "AsyncCompilation: " or "(null): "). It also extends existing
tests to check for the precise error message more thoroughly to detect
changes or nondeterminism earlier.
