From-SVN: r258834

This PR is another regression caused by the removal of the simple_iv
check in dr_analyze_innermost for BB analysis.  Without splitting out
the step, we weren't able to find an underlying object whose alignment
could be increased.

As with PR81635, I think the simple_iv was only handling one special
case of something that ought to be more general.  The more general
thing here is that if the address can be analysed as a scalar
evolution, and if all updates preserve alignment N, it's possible
to align the address to N by increasing the alignment of the base
object to N.  That applies also to outer loops, and to both loop
and BB analysis.

I wasn't sure where the new functions ought to live, but tree-data-ref.c
seemed OK since (a) that already does scev analysis on addresses and
(b) you'd want to use dr_analyze_innermost first if you were analysing
a reference.

This bug has been reported against GCC 7.3.0 but it is latent in all release branches and on trunk.
We underestimate the length of the LRSH instruction in Thumb state.
Unlike other load instructions LDRSH can be encoded in 16 bits only when using a register offset.
In the testcase we have "ldrsh   r2, [r4]" being assigned a length of 2, which is wrong.
So we don't calculate branch ranges properly and cause the assembler error.

The fix is to make the unaligned_loadhis insn similar to the *arm_extendqihi_insn insn that outputs an LDRSB.
Just remove the wrong 2-byte alternative. I don't think this is worth inventing a new "register-offset-only" constraint.
This also makes the patch safer for backporting.

Bootstrapped and tested on arm-none-linux-gnueabihf.
