This patch uses global rather than member operators for wide-int.h,
so that the first operand can be a non-wide-int type.
The patch also removes the and_not and or_not member functions.
It was already inconsistent to have member functions for these
two operations (one of which was never used) and not other wi::
ones like udiv. After the operator change, we'd have the additional
inconsistency that "non-wi & wi" would work but "non-wi.and_not (wi)"
wouldn't.

compiler: drop special handling of unexported func/var assembler names
For example, for the package math/big, we used to generate unexported
names as `big.trim` and exported names as `math_big.NewInt`. After
this change we will use `math_big` consistently.
Consolidate all symbol name handling into the new file names.cc. This
is intended to define all the names that will appear in the generated
assembly code. Names that will not appear in the assembly code, such
as local variable names or label names, remain where they are.
This consolidation is not intended to change any of the existing
symbol names. Tested by building without and without this patch and
comparing the libgo symbol table.
