8d4059f9b3 test: Make gccgo believe that the variables can change.
This test is supposed to test runtime behaviour.  However,
gccgo is smart enough to see that the variables are local to
the package and that they never change.  Add a function so
that gccgo thinks that the variables can in fact vary, so that
the test works at runtime as expected.

323a116fd0 libmach: fix new thread race with Linux
If you look at the sequence of values returned
by waitpid, it simply tells us about the child of
clone before it tells us that the parent called clone.
There's nothing we can do but assume unexpected
tids are newly cloned children.

Tested with 6prof on godoc.

Fixes #251.

0aa2317096 arm: work around reg allocator bug in 5g, in two parts.
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.

9d93d57465 test: Run garbage collector before testing malloc numbers.
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.
