[Bug lto/41715] New: VIEW_CONVERT_EXPR use for mismatched prevailing decl replacement doesn't work

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Because we end up with VIEW_CONVERT_EXPRs in places where we do not want them.

lto1: internal compiler error: in remap_decls, at tree-inline.c:576

 internal compiler error: tree check: expected tree that contains 'decl common'
structure, have 'view_convert_expr' in remap_decls, at tree-inline.c:542

 internal compiler error: tree check: expected tree that contains 'decl common'
structure, have 'view_convert_expr' in remove_unused_scope_block_p, at
tree-ssa-live.c:450

Breaks 200.sixtrack and 191.fma3d.
