[PATCH ARM] Fix big-endian half insns

Subject: [PATCH ARM] Fix big-endian half insns
Organization: ARM Ltd.
Reply-to: Richard dot Earnshaw at arm dot com

A NetBSD developer using a big-endian ARM system recently pointed out that 
the compiler was generating incorrect code for some half-word operations.  
This patch fixes the problem by eliminating use of subreg in the md expand 
patterns (using gen_lowpart instead).

This patch is reported to have solved the problems, and has been tested by 
me on an arm-elf cross for both big and little-endian.

R.

	* arm.md (storehi): Avoid use of explicit subreg.
	(storehi_bigend, storeinthi, movhi_bigend): Likewise.
