  Log Message:
  -----------
  [Sema] Make C++ functional-style cast warn about dropped qualifiers (-Wcast-qual)

Functional-style cast (i.e. a simple-type-specifier or typename-specifier
followed by a parenthesize single expression [expr.type.conv]) is equivalent
to the C-style cast, so that makes sense they have identical behavior
including warnings.

This also matches GCC https://godbolt.org/z/b8Ma9Thjb.
