Continuing moving macros out of math-tests.h to smaller headers
following typo-proof conventions instead of using #ifndef, this patch
moves the EXCEPTION_TESTS_* macros for individual types out to their
own sysdeps header.
As with ROUNDING_TESTS_*, there is no need to define these macros if
FE_ALL_EXCEPT == 0 and the individual exception macros are undefined;
thus, math-tests-exceptions.h headers are only needed for soft-float
ARM and RISC-V, while the other cases that defined these macros do not
need to do so (and the associated math-tests.h headers are thus
removed without needing replacement by math-tests-exceptions.h
headers).
Tested with build-many-glibcs.py.

Continuing moving macros out of math-tests.h to smaller headers
following typo-proof conventions instead of using #ifndef, this patch
moves the ROUNDING_TESTS_* macros for individual types out to their
own sysdeps header.
In the soft-float case where FE_TONEAREST is the only rounding mode
macro defined, there is no need to define ROUNDING_TESTS_*; it is only
necessary when rounding modes macros are defined that may not be
supported at runtime. Thus, the ROUNDING_TESTS_* definitions for some
configurations are just removed, not moved to new
math-tests-rounding.h headers; the only architectures needing
math-tests-rounding.h are those where the macros are defined in
bits/fenv.h because of the possibility of a soft-float compilation
using a hard-float glibc with the same ABI (i.e., ARM and RISC-V).
The test-*-vlen*.h headers, by using #undef, do not yet follow
typo-proof conventions (but they no longer implicitly rely on being
included before math-tests.h, and this area can always be cleaned up
further in future).

I've moved the ARM port from ports to the main sysdeps hierarchy.
Beyond the README update, the move of the files was simply
git mv ports/sysdeps/arm sysdeps/arm
git mv ports/sysdeps/unix/arm sysdeps/unix/arm
git mv ports/sysdeps/unix/sysv/linux/arm sysdeps/unix/sysv/linux/arm
and in addition to the ChangeLog entries here, I put a note at the top
of ports/ChangeLog.arm similar to that at the top of
ChangeLog.powerpc. There is deliberately no NEWS change, as I think
it makes the most sense to put in a general note above all ports
having moved if we can achieve that for 2.20.
Tested that disassembly of installed shared libraries for arm is the
same before and after this patch, except for data (not instructions)
in ld.so (there are assertions in sysdeps/arm/dl-machine.h, and the
path by which that file is found, and so by which it appears in the
assertion message, changes as a result of the move).
* sysdeps/arm: Move directory from ports/sysdeps/arm.
* sysdeps/unix/arm: Move directory from ports/sysdeps/unix/arm.
* sysdeps/unix/sysv/linux/arm: Move directory from
ports/sysdeps/unix/sysv/linux/arm.
* README: Update listing for arm-*-linux-gnueabi.
ports/ChangeLog.arm:
* sysdeps/arm: Move directory to ../sysdeps/arm.
* sysdeps/unix/arm: Move directory to ../sysdeps.arm.
* sysdeps/unix/sysv/linux/arm: Move directory to
../sysdeps/unix/sysv/linux/arm.
