gdb: recognize new DWARF attributes: defaulted, deleted, calling conv.
Extend GDB's internal representation of types to include the
DW_AT_calling_convention, DW_AT_defaulted, and DW_AT_deleted attributes
that were introduced in DWARF5.
These attributes will be helpful in a future patch about infcall'ing
functions with call-by-value parameters. GDB will use the attributes
to decide whether the type of a call-by-value parameter is implicitly
pass-by-reference.
gdb/ChangeLog:
2019-12-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>
* dwarf2read.c (dwarf2_add_member_fn): Read the DW_AT_defaulted

(read_structure_type): Read the DW_AT_calling_convention attribute
of a type.
(is_valid_DW_AT_defaulted): New function.
(is_valid_DW_AT_calling_convention_for_type): New function.
* gdbtypes.h: Include dwarf2.h.
(struct fn_field)<defaulted>: New field to store the
DW_AT_defaulted attribute.
(struct fn_field)<is_deleted>: New field to store the

(struct cplus_struct_type)<calling_convention>: New field to store
the DW_AT_calling_convention attribute.
(TYPE_FN_FIELD_DEFAULTED): New macro.
