middle-end/99122 - Issues with VLA parameter inlining

The following instructs IPA not to inline calls with VLA parameters
and adjusts inlining not to create invalid view-converted VLA
parameters on mismatch and makes the error_mark paths with debug
stmts actually work.

The first part avoids the ICEs with the testcases already.
