[PATCH v2 00/14] ARM improvements


I believe I've now addressed all of the comments to date.

Patches 4-8 have been approved, but they touch the same code
as patches 1-3, so I'm not rearranging them.

Patch 1 -- Spurious whitespace changes removed.
Patch 2 -- I never saw a review for this one?
Patch 3 -- Totally rewritten, in preparation for new patch for hard-tp.
Patch 6 -- Review mentioned deleting __APCS_32__, but this was already
	   done in patch 7, so I didn't rearrange that.
Patch 9-10 -- New.
Patch 11-12 -- Micro-optimization suggestions from Mans Rullgard applied.
Patch 14 -- Adjusted to avoid r9.

I've yet to test the string routines on big-endian.  I'll delay
re-posting those until I have done so.
