Also:
* document special cases for Frexp and Ldexp
* handle ±Inf in Ldexp
* correctly return -0 on underflow in Ldexp
* test special cases for Ldexp
* test boundary cases for Frexp, Ilogb, Ldexp, and Logb

Minor cleanup:
  - removed a duplicate test case
  - added a function to remove repeated code
  - for consistency, replaced "return nil" with a panic at an
    unreachable point

Fixes #1428.

Have to set #defines correctly to get correct value.
Otherwise get a mask for use in implementing WIFSTOPPED(status).

Changed WSTOPPED definition in os because on
OS X WSTOPPED and WUNTRACED have different values
even though they seem to mean the same thing.

The fault was lucky: when it wasn't faulting it was silently
copying a word from some other block and later putting
that same word back.  If some other goroutine had changed
that word of memory in the interim, too bad.

The ARM code was inconsistent about whether the
"argument frame" included the saved LR.  Including it made
some things more regular but mostly just caused confusion
in the places where the regularity broke.  Now the rule
reflects reality: argp is always a pointer to arguments,
never a saved link register.

Renamed struct fields to make meaning clearer.

Running ARM in QEMU, package time's gotest:
  * before: 27/58 failed

This defines crosscall2 in a way that matches that real
definition, and also defines _cgo_allocate and _cgo_panic to
indicate that they are available to be called by code compiled
with gcc.

In this specific package crosscall2 is already defined in a .S
file anyhow.  This avoids a warning about mismatched
alignment.

Introduced a printer mode (pmode) type and corresponding
pmode values which permit easy toggling of the current
printer mode for fine-tuning of layout.

Use the printer mode to disable potential introduction of
line breaks before a closing '}' in composite literals.

Added extra test case. Applied gofmt to src and misc.
