3f71b7f1f6 implements #766; 
expressions such as Type.field are now recognised by the compiler.
This also fixes a bug, preventing the user-defined to check for the presence of
regular fields in addition to procs

e3f53409f6 proc redefinition search based on the type system instead of on sloppy AST matching 
This will work the same for procs/templates/macros/etc, having arbitrary mix of implicit
and explicit generics (as long as the symbols are equivalent for the purposes of overload
resolution, they will be detected as redefinitions)

fixes tgeneric

1d02f2ea53 wip type class reforms (the compiler bootstraps fine) 
* replace tfAny and tfAll with tyAnd and tyOr
* integrate matchTypeClass into typeRel
* introduce tyBuiltInTypeClass to handle types such as tuple, object, proc, etc

299cefdc98 make the current PContext accessible through TCandidate 
the goal here is to remove all the hacks from ParamTypeMatch and to handle
all type matching in typeRel (the context there is required to evaluate any static
params and to run the compilation tests of user-defined type classes)

027f30610e static params: expr[T] is now static[T] 
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.

fee2a7ecfa Experimental support for delayed instantiation of generics 
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.
