Does this issue affect you?

I didn't commit or send change to list as this mainly affects
32-bit hpux target which has been disabled.

Indeed an obvious bug in the testcase, prone to fail on any strict-align
target.

With -fno-ipa-sra, the test always fails since it was first introduced.

The test passes if I change the argument of get_a from SS to SSS.  Then,
it handles the misaligned argument:

get_a:
.PROC
.CALLINFO FRAME=0,NO_CALLS
.ENTRY
.stabn  68,0,14,L$M0001-L$FBB0001
L$M0001:

or %r20,%r19,%r20
