This patch fixes a bug in RISC-V's memcpy implementation where an
integer wraparound occurs when src + size < 8 * sizeof(long), causing
the word-sized copy loop to be incorrectly entered.

If we had architecture-specific exception bits, we could just set them
to match the processor, but instead ieeefp.h is shared by all targets
so we need to map between the public values and the register contents.

This makes the fpsetround function actually do something rather than
just return -1 due to the default 'fall-through' behavior of the switch
statement.

This patch adds implementations of memcpy, memmove, memset and strcmp
optimized for size. The changes have been tested in
riscv/riscv-gnu-toolchain by riscv-dejagnu with
riscv-sim.exp/riscv-sim-nano.exp.
This macro selects a compiler option that disables recognition of
common memset/memcpy patterns and converting those to direct
memset/memcpy calls.

Subject: [PATCH] nvptx port
This port adds support for Nvidia GPU's, which are primarily used as
offload accelerators in OpenACC and OpenMP.
- For prevent confuse about what BSD license variant we used, 2- or
3-clause license, we change the license to FreeBSD license to make
it unambiguously refers to the 2-clause license.
