 Suppressions for V8 correctness fuzzer failures.
 
 We support three types of suppressions:
 1. Ignore test case by pattern.
 Map a regular expression to a bug entry. A new failure will be reported

 # Ignore by output pattern. Map from config->bug->regexp. Config '' is used
 # to match all configurations. Otherwise use either a compiler configuration,
 # e.g. fullcode or validate_asm or an architecture, e.g. x64 or ia32 or a
 # comma-separated combination, e.g. x64,fullcode, for more specific
 # suppressions.
 # Bug is preferred to be a crbug.com/XYZ, but can be any short distinguishable
 # label.
 # Regular expressions are assumed to be compiled. We use regexp.search.
