ARM: Correct several inconsistencies with ldrd and strd

* lib/jit_disasm.c: Change thumb or arm disassemble based on
	jit code before disassembly.

	* lib/jit_arm-cpu.c: Correct reversed arguments to LDRD and
	STRD instructions, and correct checking for support of those.

	* lib/jit_arm-swf.c: Correct wrong use of LDRD and STRD and
	only use those if the register is even.

	* check/check.arm.swf.sh, check/check.arm4.swf.sh: New files
	to test LDRD and STRD, as well as the alternate code path
	when those are not available, in the .arm4. test case.

	* check/Makefile.am: Update for the new test cases.
