rs6000: Fix allocate_stack in a corner case (PR91289)
When we have -fstack-limit-symbol with sysv we can end up with a non-
existing instruction (you cannot add an immediate to register 0). Fix
this by using register 11 instead. It might be used for something else
already though, so save and restore its value around this. In
optimizing compiles these extra moves are usually removed again: the
restore by cprop_hardreg, and then the save by rtl_dce.

allowing 'reference' and 'const_reference' types to be obtained from an

Fix incorrect merge of conflictant names in `dump_graphviz`

Arm: Fix arm libsanitizer bootstrap failure
Glibc has recently introduced changed to the mode field in ipc_perm
in commit
2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this
means that the mode field no longer has the same size.
This causes an assert failure against libsanitizer's internal copy
of ipc_perm. Since this change can't be easily detected I am adding
arm to the list of targets that are excluded from this check. libsanitizer
doesn't use this field (and others, it in fact uses only 1 field) so this check
can be ignored.
Padding bits were used by glibc when the field was changed so sizeof and offsets
of the remaining fields should be the same.

Now the former matches a real insn in Arm state, using the RSC

recognize the canonicalized form. Nevertheless, given the above
