Libc on Darwin/ARM has a buggy implementation of ldexp and frexp
that could not handle denormal numbers.
Also disable VFP runfast (flush-to-zero) mode so that the gc
compiler can correctly handle denormal constants used in math and
strconv tests.

The build was broken on Plan 9 after the
CL 2994, because of the use of getfields
in src/liblink/go.c.
This happened when building 8l, because
getfield was part of lib9 and tokenize
was part of the Plan 9 libc. However,
both getfields and tokenize depend on
utfrune, causing an incompatibility.
This change enables the build of tokenize
as part of lib9, so it doesn't use
tokenize from the Plan 9 libc anymore.

This fixes a couple of problems that occur when the linker
removes its temporary directory on Windows. The linker only
creates and removes a temporary directory when doing external
linking. Windows does not yet support external linking.
Therefore, these problems are only seen when using a
cross-compiler hosted on Windows.
In lib9, FindFirstFileW returns just the file name, not the
full path name. Don't assume that we will find a slash.
Changed the code to work either way just in case.
In ld, Windows requires that files be closed before they are
removed, so close the output file before we might try to
remove it.
Fixes#8723.

This CL adds a flag parser that matches the semantics of Go's
package flag. It also changes the linkers and compilers to use
the new flag parser.
Command lines that used to work, like
8c -FVw
6c -Dfoo
5g -I/foo/bar
now need to be split into separate arguments:
8c -F -V -w
6c -D foo
5g -I /foo/bar
The new spacing will work with both old and new tools.
The new parser also allows = for arguments, as in
6c -D=foo
5g -I=/foo/bar
but that syntax will not work with the old tools.
In addition to matching standard Go binary flag parsing,
the new flag parser generates more detailed usage messages
and opens the door to long flag names.
The recently added gc flag -= has been renamed -complete.
