* config/rs6000/rs6000-modes.def (toplevel): Rework the 128-bit
floating point modes, so that IFmode is numerically greater than
TFmode, which is greater than KFmode using FRACTIONAL_FLOAT_MODE
to declare the ordering. This prevents IFmode from being
converted to TFmode when long double is IEEE 128-bit on an ISA 3.0
machine. Include rs6000-modes.h to share the fractional values
between genmodes* and the rest of the compiler.

When deduction guides are supported by the compiler (i.e. for C++17 and
later) replace two basic_string constructors by constrained function
templates as required by LWG 3075. In order to ensure that the pre-C++17
non-template constructors are still exported from the shared library
define a macro in src/c++11/string-inst.cc to force the non-template
declarations (this isn't strictly needed yet, because the string
instantiations are compiled with -std=gnu++11, but that is likely to
change).

Add multilib variants for -march=rv64imafd, e.g. to support the BOOMv2 core.
Add -mcmodel=medany as a variant of the 64-bit multilibs for RTEMS. The
rationale for this change is that several existing RISC-V chips map the
RAM at 0x80000000. In RTEMS, we do not use virtual memory, so
applications will run at this location which is outside the +-2GiB range
in a 64-bit configuration.
