This also fixes the semantics of some corner cases with the empty
match. TODOs for genericReplacer in the tests are fixed.

Give the right name for errors, and add a test to check we're
getting the errors we expect.
Also fix an ordering bug (calling add after stopParse) that
caused a nil indirection rather than a helpful error.

Command.Start could crash before if no fds were available
because a nil *os.File of /dev/null was added to the cleanup
list, which crashed before returning the proper error.

Strings happen to be represented similarly to
byte slices internally, but they don't quite
behave like them: While strings can be indexed,
sliced, and have their len() taken like byte
slices, string elements are not addressable,
make() and cap() is not supported, range loops
operate differently, and they are immutable (and
thus behave like values rather then references).
Fixes#4018.

instead of variables. Several reasons:
- Encourage users of the API to minimize the number of creations and reuse Collate objects.
- Don't rule out the possibility of using initialization code for collators. For some locales
it will be possible to have very compact representations that can be quickly expanded
into a proper table on demand.
Other changes:
- Change name of root* vars to main*, as the tables are shared between locales.
- Added Locales() method to get a list of supported locales.

X509KeyPair wasn't really supposed to allow the certificate and
key to be in the same file, but it did work if you put the key
first. Since some HTTPS servers support loading keys and certs
like this, this change makes it work in either order.

This fixes a problem with ELF tools thinking they know the
format of the symbol table, as we do not use any of the
standard formats for that table.
This change will probably annoy the Plan 9 users, but I
believe there are other incompatibilities already that mean
they have to use a Go-specific nm.

go tool dist env -w is supposed to print a Windows batch file.
Normally Windows will execute batch files without \r before \n,
but issue 3060 reports that if the file ends up containing paths
written in Chinese, Windows 7 cannot execute it without the \r.
So add the \r.

It is enough to load directly the data word and the itab word

Removes an extra LEAL/LEAQ instructions there and usually saves
a useless temporary in the idiom
if err := foo(); err != nil {...}
Generated code is also less involved:
MOVQ err+n(SP), AX
CMPQ AX, $0
(potentially CMPQ n(SP), $0) instead of
LEAQ err+n(SP), AX
CMPQ (AX), $0
