Properly pseudo-ize the ARM LDMIA_RET instruction. This has the nice side-
...
effect that we get proper instruction printing using the "pop" mnemonic for it.

Fix a bug which prevented tail merging of return instructions in
...
beneficial cases. See the changes in test/CodeGen/X86/tail-opts.ll and
test/CodeGen/ARM/ifcvt2.ll for details.
The fix is to change HashEndOfMBB to hash at most one instruction,
instead of trying to apply heuristics about when it will be profitable to
consider more than one instruction. The regular tail-merging heuristics
are already prepared to handle the same cases, and they're more precise.
Also, make test/CodeGen/ARM/ifcvt5.ll and
test/CodeGen/Thumb2/thumb2-branch.ll slightly more complex so that they
continue to test what they're intended to test.
And, this eliminates the problem in
test/CodeGen/Thumb2/2009-10-15-ITBlockBranch.ll, the testcase from
PR5204. Update it accordingly.

Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.
...
This does not move entirely to UAL syntax, since the default "increment after"
suffix is empty but we still use "IA" for that.
