Ignore signals while we are spawning a new thread. Previously, a
signal arriving just before runtime.minit setting up the signal
handler triggers a "double fault" in signal trampolining.

This is a manual undo of CL 5674098.
It does not implement the even less strict spec
that we just agreed on, but it gets us back where
we were at the last weekly.

cc: add #pragma textflag to set it
runtime: mark mheap to go into noptr-bss.
        remove special case in garbage collector

Remove the ARM from.flag field created by CL 5687044.
The DUPOK flag was already in p->reg, so keep using that.

Otherwise test/nilptr.go creates a very large binary.
Should fix the arm build.

Or, depending on your point of view, make the

A fault during malloc might lead to the program's

by other low-level libraries, like collate.  Extra care has been given to optimize the performance
of normalizing to NFD, as this is what will be used by the collator.  The overhead of checking
whether a string is normalized vs simply decomposing a string is neglible.  Assuming that most
strings are in the FCD form, this iterator can be used to decompose strings and normalize with
minimal overhead.
