We don't need RV32 specific floating point functions, instead make them
generic for RISC-V.

Both RV32 and RV64 should have the same libm-test-ulps, so consolidate
them into a single file.

The 32-bit and 64-bit variants of RISC-V share the same name - "RISC-V"
- when generating the libm error table for the info pages. This
collision, and the way how the table is generated, mean that the values
in the final table for "RISC-V" may be either for the 32- or 64-bit
variant, with no indication as to which.
As an additional side-effect, this makes the build non-reproducible, as
the error table generated is dependent upon the host filesystem
implementation.
To solve this issue, the libm-test-ulps-name files for both variants
have been modified to include their word size, so as to remove the
collision and provide more accurate information in the table.
An alternative proposed was to merge the two variants' ULP values into a
single file, but this would mean that information about error values is
lost, as the two variants are not identical. Some differences are
considerable, notably the values for the exp() function are large.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 7061 files FOO.
I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't

This patch lays out the top-level organisation of the RISC-V 32-bit port.
It provides all the Implies files as well as various other fragments of
the build infrastructure.

Conversions from a float to a long long on 32-bit RISC-V (RV32) may not
raise the correct exceptions on overflow, it also may raise spurious
"inexact" exceptions on non overflow cases. This patch fixes the
problem, similarly to the fix for MIPS, ARM and S390.

Add a libm-test-ulps for RV32, this is the same as the RV64 one.
This dosn't match what is generated by running `make regen-ulps` on RV32
QEMU, but the current in tree RV64 doesn't match that either.
