* replace tfAny and tfAll with tyAnd and tyOr
* integrate matchTypeClass into typeRel
* introduce tyBuiltInTypeClass to handle types such as tuple, object, proc, etc
This introduces tyStatic and successfully bootstraps and handles
few simple test cases. Static params within macros are no longer
treated as PNimrodNodes - they are now equivalent to constants
of the designated type.
This commit requires further investigation.
Fixing semExpr(nkCall) once and for all to work with sym-choices and to
allow overloading with immediate templates and macros will probably set
this straight too.
This postpones the semantic pass over the generic's body until
the generic is instantiated. There are several pros and cons for
this method and the capabilities that it enables may still be possible
in the old framework if we teach it a few new trick. Such an attempt
will follow in the next commits.
pros:
1) It allows macros to be expanded during generic instantiation that
will provide the body of the generic. See ``tmacrogenerics``.
2) The instantiation code is dramatically simplified. Dealing with unknown
types in the generic's body pre-pass requires a lot of hacky code and error
silencing in semTypeNode. See ``tgenericshardcases``.
cons:
1) There is a performance penalty of roughly 5% when bootstrapping.
2) Certain errors that used to be detected in the previous pre-pass won't
be detected with the new scheme until instantiation.
the lambda lifting was trying too hard to ignore generic prods
isGenericRoutine was producing false-negatives and only
this allowed for some of the warning and error messages
to be triggered.
some files with mixed line endings were fixed
