Add missing format for built-in floating-point types

Browse source 
Many callers of init_float_type and arch_float_type still pass a NULL
floatformat.  This commit changes those callers where the floatformat
that is supposed to be use is obvious.  There are two categories where
this is the case:

- A number of built-in types are intended to match the platform ABI
  floating-point types (i.e. types that use gdbarch_float_bit etc.).
  Those places should use the platform ABI floating-point formats
  defined via gdbarch_float_format etc.

- A number of language built-in types should simply use IEEE floating-
  point formats, since the language actually defines that this is the
  format that must be used to implement floating-point types for this
  language.  (This affects Java, Go, and Rust.)  The same applies for
  to the predefined "RS/6000" stabs floating-point built-in types.

gdb/ChangeLog:

	* ada-lang.c (ada_language_arch_info): Use gdbarch-provided
	platform ABI floating-point formats for built-in types.
	* d-lang.c (build_d_types): Likewise.
	* f-lang.c (build_fortran_types): Likewise.
	* m2-lang.c (build_m2_types): Likewise.
	* mdebugread.c (basic_type): Likewise.

	* go-lang.c (build_go_types): Use IEEE floating-point formats
	for language built-in types as mandanted by the language.
	* jv-lang.c (build_java_types): Likewise.
	* rust-lang.c (rust_language_arch_info): Likewise.
	* stabsread.c (rs6000_builtin_type): Likewise.
