Tobias Tebbi 0ba115e6a9 Reland^2 "[flags] warn about contradictory flags"
This is a reland of d8f8a7e210
Change compared to last reland:
- Do not check for d8 flag contradictions in the presence of --fuzzing
- Allow identical re-declaration of --cache=*

Original change's description:
> Reland "[flags] warn about contradictory flags"
>
> This is a reland of b8f9166664
> Difference to previous CL: Additional functionality to specify
> incompatible flags based on GN variables and extra-flags, used
> to fix the issues that came up on the waterfall.
>
> This also changes the rules regarding repeated flags: While
> explicitly repeated flags are allowed for boolean values as long
> as they are identical, repeated flags or explicit flags in the
> presence of an active implication are disallowed for non-boolean
> flags. The latter simplifies specifying conflict rules in
> variants.py. Otherwise a rule like
>
> INCOMPATIBLE_FLAGS_PER_EXTRA_FLAG = {
>   "--gc-interval=*": ["--gc-interval=*"],
> }
>
> wouldn't work because specifying the same GC interval twice
> wouldn't actually count as a conflict. This was an issue with
> test/mjsunit/wasm/gc-buffer.js, which specifies
> --gc-interval=500 exactly like the extra flag by the stress bot.
>
> Also, this now expands contradictory flags checking to d8 flags
> for consistency.

JavaScript tests with expected output

Tests in test/message pass if the output matches the expected output. Message tests are particularly useful when checking for exact error messages.

Tests and their expected output must have the same filename, with the .js and .out extension.

foo.js
foo.out

All tests must end with an exception. The test runner does not handle output from multiple runs, e.g., --stress-opt. Without an exception, the output will be generated several times and the comparison will fail.

You can use a regex in the expected output instead of the exact path:

*%(basename)s:7: SyntaxError: Detected cycle while resolving name 'a'

Empty lines are ignored in the comparison, but whitespaces are not.

Exact details of the test runner are in testcfg.py.
