GCC's <float.h> includes various macros for decimal floating-point
types, defined if __STDC_WANT_DEC_FP__, as defined in TS 24732.
TS 18661-2 and C2X make some changes to those macros. In TS 18661-2,
they are to be defined if __STDC_WANT_IEC_60559_DFP_EXT__, and the
*_SUBNORMAL_MIN macros are renamed to *_TRUE_MIN. In C2X, the macros
are to be defined whenever DFP is supported, without needing any
feature test macro to be defined.
This patch updates the header accordingly. There is no existing
predefined macro for whether the target supports DFP; rather than
adding a new macro for that purpose, this patch changes the predefined
macros used in <float.h> so that they are only defined when DFP is
supported and thus can be used as conditionals; this is the same way
predefined macros for _FloatN and _FloatNx types work. Although
formally TR 24732 and TS 18661-2 say nothing about implementations
lacking DFP support, it seems appropriate to avoid defining the macros
in <float.h>, in the absence of DFP support, even if the respective
feature test macros are defined.
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Also tested
the c2x-float-no-dfp-* tests for aarch64-linux-gnu to make sure they
do pass in a no-DFP configuration.

This patch uses the support for pretty-printing escaped URLs added in
the previous patch (PR 87488) so that in a sufficiently capable terminal
the [-Wname-of-option] emitted at the end of each diagnostic becomes a
hyperlink to the documentation for that option on the GCC website.
I've tested it with Fedora 30's GNOME Terminal (3.32.2 with VTE 0.56.3);
the option text is printed with a dotted underline, hovering shows the
URL, and on right-clicking it offers menu items to visit/copy the URL.

* exp_ch7.adb (Check_Unnesting_In_Decls_Or_Stmts): When
encountering a loop at the top level of a package declaration
list (that is, within the declarations of a package spec or
body) that has nested subprograms, call Unnest_Loop to create a
new library-level procedure that will contain the loop, to allow
for proper handling of up-level references from within nested
subprograms, such as to loop parameters.
(Unnest_Loop): New procedure that takes a loop statement and
creates a new procedure body to enclose the loop statement,
along with generating a call to the procedure.

* sem_ch13.adb (Adjust_Record_For_Reverse_Bit_Order): Do not use
the Esize of the component to compute its layout, but only the
Component_Clause. Do not issue a warning for the _Tag
component. Also set the Esize of the component at the end of
the layout.
(Analyze_Record_Representation_Clause): Remove Hbit local
variable. Lay out the Original_Record_Component only if it's
distinct from the component.
(Check_Record_Representation_Clause): Fix off-by-one bug for the
Last_Bit of the artificial clause built for the _Tag component.
