This adds support for the bfloat16 datatype, which can be seen as a short
version of FP32, skipping the least significant 16 bits of the mantissa.
Since the datatype is currently only supported by the AVX512 registers,
the printing of bfloat16 values is only supported for xmm, ymm and zmm
registers.

Getting the bounds of an array (or string) type is a common operation,
and is currently done through its index type:
my_array_type->index_type ()->bounds ()
I think it would make sense to let the `type::bounds` methods work for
arrays and strings, as a shorthand for this. It's natural that when
asking for the bounds of an array, we get the bounds of the range type
used as its index type. In a way, it's equivalent as the now-removed
TYPE_ARRAY_{LOWER,UPPER}_BOUND_IS_UNDEFINED and
TYPE_ARRAY_{LOWER,UPPER}_BOUND_VALUE, except it returns the
`range_bounds` object. The caller is then responsible for getting the
property it needs in it.
I updated all the spots I could find that could take advantage of this.
Note that this also makes `type::bit_stride` work on array types, since
`type::bit_stride` uses `type::bounds`. `my_array_type->bit_stride ()`
now returns the bit stride of the array's index type. So some spots
are also changed to take advantage of this.

Remove the macro and add a `bit_stride` method to `struct range_bounds`,
which does the byte -> bit conversion if needed.
Add a convenience `bit_stride` method to `struct type` as well. I don't
really understand why the bit/byte stride is stored in the data
structure for bounds. Maybe it was just put there because
`range_bounds` was already a data structure specific to TYPE_CODE_RANGE
types? If the stride is indeed not related to the bounds, then I find
it more logical to do `my_range_type->bit_stride ()` than
`my_range_type->bounds ()->bit_stride ()`, hence the convenience
function on `struct type`.

Add setters, to ensure that the kind and value of the property are
always kept in sync (a caller can't forget one or the other). Add
getters, such that we can assert that when a caller accesses a data bit
of the property, the property is indeed of the corresponding kind.
Note that because of the way `struct dynamic_prop` is allocated
currently, we can't make the `m_kind` and `m_data` fields private. That
would make the type non-default-constructible, and we would have to call
the constructor when allocating them. However, I still prefixed them
with `m_` to indicate that they should not be accessed from outside the
class (and also to be able to use the name `kind` for the method).

The next patch will remove `FIELD_TYPE` completely.
Note that because of the name clash between the existing field named
`type` and the new method, I renamed the field `m_type`. It is not
private per-se, because we can't make `struct field` a non-POD yet, but
it should be considered private anyway (not accessed outside `struct
field`).

Since dwarf2_per_cu_data objects are going to become
objfile-independent, the backlink from dwarf2_per_cu_data to one
particular objfile must be removed. Instead, users of
dwarf2_per_cu_data that need an objfile must know from somewhere else in
the context of which objfile they are using this CU.
This also helps remove a dwarf2_per_cu_data::dwarf2_per_objfile
reference (from where the objfile was obtained).
Note that the dwarf2_per_cu_data::objfile method has a special case to
make sure to return the main objfile, if the objfile associated to the
dwarf2_per_cu_data is a separate debug objfile. I don't really know if
this is necessary: I ignored that, and didn't see any regression when
testing with the various Dejagnu boards with separate debug info, so I
presume it wasn't needed. If it turns out this was needed, then we can
have a helper method on the objfile type for that.

Replace all uses of it by type::field.
Note that since type::field returns a reference to the field, some spots
are used to assign the whole field structure. See ctfread.c, function
attach_fields_to_type, for example. This is the same as was happening
with the macro, so I don't think it's a problem, but if anybody sees a
really nicer way to do this, now could be a good time to implement it.

Remove all uses of the `TYPE_FIELDS` macro. Replace them with either:
1) type::fields, to obtain a pointer to the fields array (same as

Add the `num_fields` and `set_num_fields` methods on `struct type`, in

I think that in the future, we should consider making the interface of
`struct type` better. For example, right now it's possible for the
number of fields property and the actual number of fields set to be out

just translate from macros to methods.

Remove this macro, which abstracts how to obtain the dyn_prop_list of a

don't think it's needed, as the only code that accesses the dynamic prop
