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

When reading along the article, the extra code added in the final

example, which will cause an error, unless the readers looks at the
entirety of final.go to see the import added.
The file shown to the users no longer has the extra flags. The testing
code is now in a patch that gets applied to final.go in order to create
final-test.go. This is the file that will be used to test the code,
matching final.go as much as possible.

This CL removes the remaining visible uses of the "architecture letter" concept.
(They are no longer in tool names nor in source directory names.)
Because the architecture letter concept is now gone, delete GOCHAR
from "go env" output, and change go/build.ArchChar to return an
error always.
The architecture letter is still used in the compiler and linker sources
as a clumsy architecture enumeration, but that use is not visible to
Go users and can be cleaned up separately.
