PR c++/27506
* typeck.c (decay_conversion): Convert bitfields to their declared
types here.  Improve documentation.  Avoid use of cp_convert.
(default_conversion): Make it static.  Perform integral promotions
before lvalue-to-rvalue, function-to-pointer, and array-to-pointer
conversions.
* init.c (build_init): Remove.
(expand_default_init): Do not call rvalue.
* call.c (null_ptr_cst_p): Robustify.
(build_conditional_expr): Tidy.
* except.c (build_throw): Do not perform lvalue-to-rvalue
conversion on operand before initializing temporary.
* tree.c (convert.h): Include it.
(convert_bitfield_to_declared_type): Use convert_to_integer, not
cp_convert.
(rvalue): Don't convert bitfields to their declared type here.
* cp-tree.h (build_init): Remove.
(default_conversion): Likewise.
* typeck2.c (build_m_component_ref): Do not perform
lvalue-to-rvalue, function-to-pointer, or array-to-pointer
conversions here.  Correct error message.

Grumble.  In my queue.  I should have known better than to try to fix this the
right way. :-)

Confirmed, reduced testcase:
enum EBorderStyle
{
  BNATIVE, BHIDDEN
};
struct BorderValue
{
  enum EBorderStyle style:8;
};
enum EBorderStyle f(const struct BorderValue *border)
{
return border ?  border->style : BNATIVE;
}


I forgot if enum bitfields are a GNU extension for C++ (I know they are for C)
