c-family: Fix up -Wsizeof-pointer-memaccess ICEs [PR117230]
In the following testcases, we ICE on all 4 function calls.
The problem is using TYPE_PRECISION on vector types (but guess it
would be similarly problematic on structures/unions/arrays).
The test only differentiates between suggestion what to do, whether
to supply explicit size because sizeof (*p) for
{,{,un}signed }char *p is not very likely what the user want, or
dereferencing the pointer, so I think limiting that suggestion
to integral types is ok.

PR c/117230
* c-warn.cc (sizeof_pointer_memaccess_warning): Only compare
TYPE_PRECISION of TREE_TYPE (type) to precision of char if
TREE_TYPE (type) is integral type.
* c-c++-common/Wsizeof-pointer-memaccess5.c: New test.
