The x86_64 stv pass uses PUT_MODE to change REGs and MEMs in place to affect
all setters and users, but that is undesirable in debug insns which are
intentionally ignored during the analysis and we should keep using correct
modes (TImode) instead of the new one (V1TImode).
Note that MEMs are not shared, so twiddling the mode on any given MEM
changes one and only one object.

Note that this patch isn't trying to workaround any wrong MEM sharing,
while the other patch has been.  So, is the PR78575 ok as is?
I'll post the other updated patch in the corresponding thread.
It was an x86 patch, right?  So it's Uros's call.
