Checker: Add function isaHasFeature
Developers are now able to use hasIsaFeature("feature_name") to
check if an instruction set feature was used at compile time.
Checker will retrieve the list of features from the .cfg file. It
expects them to be dumped at the beginning of the file as a fake
compilation block in the following form:
begin_compilation
name "isa_features:feature1,-feature2"
method "isa_features:feature1,-feature2"
date 1580721972
end_compilation
Dumping that is optional. hasIsaFeature() will always return False
if that pass is not found.
