- This change implements the correct type-based equivalence
relation for aggregate types. e.g. comparison of struct
types no longer compares the anonymous fields. We do
analogous things for hash().
- equals() and eqnil() have been separated: the former panics
for uncomparable types, the latter permits comparisons of
slice/map/func types against a literal nil and is intended
for use only by "static" ssa.BinOp(EQL), not "dynamic" slice
comparisons encountered during (e.g.) interface comparisons,
which should panic regardless of operand nilness.
- we use a (global) typemap.Hasher to compute type hashes;
hashing the Type.String() value was not sound.
+ tests.
NB, this change unearthed a bug in defer/recover within
init(); it will be fixed in a followup change.

Implement Pos() method for
Values: Parameter, Capture, Phi. (Not Literal, Builtin.)
Instructions: UnOp, BinOp, Store.
'address' (an lvalue) now needs position of '*' in "*addr".
Also:
- Un-export fields Pos_ Type_ Name_ Block_ from various values/instructions.
Define NewFunction() as a temporary measure.
Will try to eliminate calls from clients...
- Remove Implements{Value,Member,Interface} marker methods.
I've decided I don't like them.
- Func.addParamObj helper.
- Various comment fixes.

They will be deleted from their current homes once this has landed.
Changes made to import paths to make the code compile, and to find
errchk in the right place in cmd/vet's Makefile.
TODO in a later CL: tidy up vet.
