debug: Fix another vector DECL_MODE ICE [PR98100]
The PR88587 fix changes DECL_MODE of vars with vector type during
inlining/cloning
when the vars are copied, so that their DECL_MODE matches their TYPE_MODE
in
the new function. Unfortunately, the following testcase still ICEs, the
var
isn't really used in the new function and so it isn't copied, but becomes
just a nonlocalized var. So we can't adjust its DECL_MODE because it
appears in multiple functions and needs different modes in between them.
The following patch changes the DEBUG_INSN creation to use TYPE_MODE
instead
of DECL_MODE for vars with vector types.

PR target/98100
* cfgexpand.c (expand_gimple_basic_block): For vars with
vector type, use TYPE_MODE rather than DECL_MODE.
* gcc.target/i386/pr98100.c: New test.
