Run libm long double tests for long double = double.
All interfaces in the glibc API ought to be covered by the testsuite,
even where they alias other interfaces. This patch arranges for libm
tests to be run for long double when it aliases double; previously
those tests were run only for the floating-point types with distinct
formats. The long double tests are made to use the double ulps values
in this case, as having a separate duplicate set of ulps for them
seems unnecessary; to accommodate that, the test-<type>.h headers now
specify the macro indexing into the ulps array explicitly instead of
having it computed from PREFIX.
Nothing special is done about vector function tests. None are
supported for any long double = double platforms, and supporting
vector functions for a type alias such as _Float32 would not simply
fall out of adding the scalar aliases for that type - it would require
vector function wrappers like those for *_finite (or, better, a new
GCC feature to allow specifying the asm name for vector functions
independently of that for scalar ones, as previously discussed), so it
seems reasonable to require the sysdeps makefile setting of
libmvec-tests to be updated if any such tests are to be run for type
aliases.
Tested for x86_64 and arm.
