The spec defines precise numeric constants which do not overflow.
Consequently, +/-Inf and NaN values were excluded. The case was not
clear for -0.0 but they are mostly of interest to determine the sign
of infinities which don't exist.
That said, the conversion rules explicitly say that T(x) (for a numeric
x and floating-point type T) is the value after rounding per IEEE-754.
The result is constant if x is constant. Rounding per IEEE-754 can
produce a -0.0 which we cannot represent as a constant.
Thus, the spec is inconsistent. Attempt to fix the inconsistency by
adjusting the rounding rule rather than letting -0.0 into the language.
For more details, see the issue below.
Open to discussion.
Fixes#12576.

The prose discussing composite literals referred to the composite
literal type with 'LiteralType', denoting the literal type's EBNF
production explicitly. Changed 'LiteralType' to 'literal type' to
remove the literal (no pun intended) connection and instead mean
the underlying type. Seems a simpler and more readable change
than referring to the underlying type everywhere explicitly.
Fixes#12717.

Make clear that this list is the list of supported systems
for binary distributions, and that other systems may be
able to build the distribution from source, in addition
to using gccgo.
Drop freebsd/arm from the list on this page.
We have never issued a binary distribution for freebsd/arm,
and we're not going to start in Go 1.5, since we don't even
have a working builder for it.
Drop freebsd/386 from the list on the page,
because we are unable to build binary distributions, per adg.
I think the wording here should probably be revised further,
but not now.

First step towards cleaning up the operator section - no language
changes. Specifically:
- Grouped arithmetic operations by types (integer, floating-point,
string), with corresponding h4 headings.
- Changed Operator precedence title from h3 to h4.
- Moved Integer Overflow section after integer operations and changed
its title from h3 to h4.
This puts things that belong together closer. No heading id's were
lost (in case of references from outside the spec).

This change allows the download page to redirect the user to
/doc/install?download=filename so the user can see installation
instructions specific to the file they are downloading.
This change also expands the "Test your Go installation" section
to instruct the user to create a workspace, hopefully leading
to less confusion down the line.
It also changes the front page download link to go directly
to the downloads page, which will in turn take them to the
installation instructions (the original destination).

The spec didn't specify several aspects of expression switches:
- The switch expression is evaluated exactly once.
- Switch expressions evaluating to an untyped value are converted
to the respective default type before use.
- An (untyped) nil value is not permitted as expression switch
value. (We could permit it relatively easily, but gc doesn't,
and disallowing it is in symmetry with the rules for var decls
without explicit type and untyped initializer expressions.)
- The comparison x == t between each case expression x and
switch expression value t must be valid.
- (Some) duplicate constant case expressions are not permitted.
This change also clarifies the following issues:
4524: mult. equal int const switch case values should be illegal
-> spec issue fixed
6398: switch w/ no value uses bool rather than untyped bool
-> spec issue fixed
11578: allows duplicate switch cases -> go/types bug
11667: int overflow in switch expression -> go/types bug
11668: use of untyped nil in switch -> not a gc bug
