CL 14315 broke the tests for parsing loosely formed remote package
metadata. Switch the parsing to use RawToken to recover the previous
behaviour that Token provided.

It could be argued that the parser should be stricter, but as remote
metadata has been readable with the parser for several years, it is
safer to change the parser to continue to accept the samples provided
in the test cases.

Currently, the xml.Decoder's Token routine returns successfully for

We compute whether two keys k1 and k2 in a map literal are duplicates by
constructing the expression OEQ(k1, k2) and calling the constant
expression evaluator on that expression, then extracting the boolean
result.

Unfortunately, the constant expression evaluator can fail for various
reasons.  I'm not really sure why it is dying in the case of 12536, but
to be safe we should use the result only if we get a constant back (if
we get a constant back, it must be boolean).  This probably isn't a
permanent fix, but it should be good enough for 1.5.2.

A permanent fix would be to ensure that the constant expression
evaluator can always work for map literal keys, and if not the compiler
should generate an error saying that the key isn't a constant (or isn't
comparable to some specific other key).

This patch has the effect of allowing the map literal to compile when
constant eval of the OEQ fails.  If the keys are really equal (which the
map impl will notice at runtime), one will overwrite the other in the
resulting map.  Not great, but better than a compiler crash.

Borrowing a suggestion from the issue listed below, we modify the lexer to
trim spaces at the beginning (end) of a block of text if the action immediately
before (after) is marked with a minus sign. To avoid parsing/lexing ambiguity,
we require an ASCII space between the minus sign and the rest of the action.
Thus:

	{{23 -}}
	<
	{{- 45}}

produces the output
	23<45

All the work is done in the lexer. The modification is invisible to the parser
or any outside package (except I guess for noticing some gaps in the input
if one tracks error positions). Thus it slips in without worry in text/template
and html/template both.

Fixes long-requested issue #9969.
