FormatSelections tries to call a nil function value if lw is nil
and the final entry in the selections array is non-nil. Luckily,
this doesn't actually happen in practice since godoc doesn't use
this combination (no line numbers, but with selections).

The previous implementation was a mess with invariants
maintained inconsistently. Essentially reimplemented
the package:
- used a circular list as internal representation for
significantly simpler implementation with fewer
special cases while maintaining the illusion of
a nil-terminated doubly linked list externally
- more precise documentation
- cleaned up and simplified tests, added test case
for issue 4103.
No changes to the API or documented semantics.
All this said, I would be in favor of removing
this package eventually. container/ring provides
a faster implementation and a simpler and more
powerful API.
Fixes#4103.

The system calls return 32-bit integers. With the recent change
in size of `int' in Go for amd64, the type conversion was not
catching `-1' return values. This change makes the conversion

In two cases, registers were allocated too early resulting
in exhausting of available registers when nesting these
operations.
The case of method calls was due to missing cases in igen,
which only makes calls but doesn't allocate a register for
the result.
The case of 8-bit multiplication was due to a wrong order
in register allocation when Ullman numbers were bigger on the
RHS.

More pieces of the typechecker code:
- Operands are temporary objects representing an expressions's
type and value (for constants). An operand is the equivalent of
an "attribute" in attribute grammars except that it's not stored
but only passed around during type checking.
- Constant operations are implemented in const.go. Constants are
represented as bool (booleans), int64 and *big.Int (integers),
*big.Rat (floats), complex (complex numbers), and string (strings).
- Error reporting is consolidated in errors.go. Only the first
dozen of lines is new code, the rest of the file contains the
exprString and typeString functions formerly in two separate
files (which have been removed).
This is a replacement CL for 6492101 (which was created without
