* tree.h (CONSTRUCTOR_BITFIELD_P): True if NODE, a FIELD_DECL, is
to be processed as a bitfield for constructor output purposes.
* output.h (initializer_constant_valid_for_bitfield_p): Declare
new function.
* varasm.c (oc_local_state): New type, output_constructor
local state to support communication with helpers.
(oc_outer_state): New type, output_constructor outer state of
relevance in recursive calls.
(output_constructor_array_range): New output_constructor helper,
extracted code for an array range element.
(output_constructor_regular_field): New output_constructor helper,
extracted code for an element that is not a bitfield.
(output_constructor_bitfield): New output_constructor helper,
extracted code for a bitfield element.  Accept an OUTER state
argument for recursive processing.  Recurse on record or array
CONSTRUCTOR values, possibly past noop conversions.
(initializer_constant_valid_for_bitfield_p): New predicate. Whether
VALUE is a valid constant-valued expression for use in a static
bit-field initializer.
(output_constructor): Rework to use helpers. Accept and honor an
OUTER state argument for recursive calls. Return total size. Be
prepared for nested constructors initializing bitfields.
(output_constant): Feed OUTER in calls to output_constructor.

ada/
* gcc-interface/utils2.c (gnat_build_constructor): Factor
out code. Use initializer_constant_valid_for_bitfield_p and
CONSTRUCTOR_BITFIELD_P for bit-fields.

testsuite/
* gnat.dg/oconst[1-6].ad[bs]: New tests. Also support for ...
* gnat.dg/test_oconst.adb: New test.
