Make muser-mode the default for LEON3

user mode ASI. This is the correct behavior for almost all LEON3 targets.

revert to assign_parms assignments using default defs
Revert the fragile and complicated changes to assign_parms designed to
enable it to use RTL assigments chosen by cfgexpand, and instead have
cfgexpand use the RTL assignments by assign_parms, keying them off of
the default defs that are now necessarily introduced for each parm and
result. The possible lack of a default def was already a problem, and
the fallbacks in place were not enough, as shown by PR67312. We now
have checking asserts in set_rtl that verify that we're assigning to
each var a piece of RTL that matches the expectations set forth by
use_register_for_decl.

Fortran passes NULL where a non-null string is expected by the pretty-printer,

incomplete diagnostic, thus it seems more user-friendly to assert only when

shrink-wrap: Handle multiple predecessors of prologue
The caller of try_shrink_wrapping wants to be returned a single edge to
put the prologue on. To make that work even if there are multiple edges
(all pointing to the PRO block) that need the prologue, add a new block
that becomes the destination of all such edges, and then jumps to PRO.
In the general case, some edges to PRO will need to be redirected, and
not all edges *can* be redirected. This adds a can_get_prologue function
that detects such cases. This then happily can also handle the "prologue
clobbers some reg that is live on the edge we want to insert it on" case.
Not all EDGE_CROSSING edges can be redirected, so handle those the same
as EDGE_COMPLEX edges.
