[PATCH] Sanopt: ignore params with DECL_HAS_VALUE_EXPR_P (PR sanitizer/86962).

[Martin Liška]

Hello.

In case of nested functions it may happen that we end up
with a PARAM_DECL with DECL_HAS_VALUE_EXPR_P. If would
skip these.

Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

Ready to be installed?
