g is not in r15 anymore.
now it's in a per-thread memory segment,
which is valid even inside a signal handler,
so we can just refer to g directly.

1) hack regalloc to leave R9 (m) and R10 (g) alone.
the real fix is tricker, but this gets us running
2) fix up the few places in the package sources that
the shortage of registers affects, by simplifying
some expressions.

all of this should be reverted when the right fix is in.

Fixes #1084.

The gccgo compiler does not always generate a "cannot use"
error message.  It only does so for named types.  Maybe that
should change, but in any case it is irrelevant for this test.

The gccgo library generates some garbage in the init routines
because it handles interfaces slightly differently.  Since the
test sets MemStats.Alloc to 0, the first time the garbage
collector runs it goes negative and the test fails.

nonblock.go wants to test nonblocking operations on

With the recursive descent parser that gccgo uses, I think
that it doesn't make sense to try to match a statement where a
statement is not expected.  If the construct is not a
statement, you will just get bizarre error messages.

Use OS rather than compiler specific flag the same way that
__FreeBSD__, __APPLE__, __OpenBSD__, and __linux__ are used.

_WIN32 is defined by GCC (and others) on windows for Win32
and Win64 applications. _WIN32 is set by default for several
other windows based compilers: DMC, MSVC, Intel, Watcom, LCC.

Although the change is for consistency, it allows the Go tools
to be compiled with non-Mingw GCC distributions and non-GCC
compilers that support the GCC extensions.
