[Sema] Disallow assigning record lvalues with nested const-qualified fields.
Summary:
According to C99 6.3.2.1p1, structs and unions with nested
const-qualified fields (that is, const-qualified fields
declared at some recursive level of the aggregate) are not
modifiable lvalues. However, Clang permits assignments of
these lvalues.
With this patch, we both prohibit the assignment of records
with const-qualified fields and emit a best-effort diagnostic.
This fixes https://bugs.llvm.org/show_bug.cgi?id=31796 .
