8357739: [jittester] disable the hashCode method

[lepestock]

JITTester often uses the hasCode method (in fact, in almost every generated test). Given that the method can be unstable between runs or in interpreted vs compiled runs, it can create false-positives.

This PR fixes the issue by adding support for method templates similar to the ones used in CompilerCommands). All of those exclude templates match (and exclude) String.indexOf(String), for example:

java/lang/::*(Ljava/lang/String;I)
*String::indexOf(*)
java/lang/*::indexOf

Additionally, the PR adds support for comments (starting from '#') and empty lines in the excludes file.
