Handle more _FloatN, _FloatNx types in type-generic strtod tests.
Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds support to type-generic strtod tests. GEN_STRTOD_TEST_FOREACH and STRTOD_TEST_FOREACH are made to handle the full set of such types. tst-strtod-round-skeleton.c is updated for those types it can handle without needing changes to the generator (i.e. those types that have already-handled formats). Tested for x86_64. * stdlib/tst-strtod.h (F16): New macro. (F32): Likewise. (F64): Likewise. (F32X): Likewise. (F64X): Likewise. (F128X): Likewise. (IF_FLOAT16): Likewise. (IF_FLOAT32): Likewise. (IF_FLOAT64): Likewise. (IF_FLOAT32X): Likewise. (IF_FLOAT64X): Likewise. (IF_FLOAT128X): Likewise. (GEN_TEST_STRTOD_FOREACH): Conditionally call macros for _Float16, _Float32, _Float64, _Float32x, _Float64x and _Float128x. (STRTOD_TEST_FOREACH): Likewise. * stdlib/tst-strtod-round-skeleton.c (CHOOSE_f32): New macro. (CHOOSE_f64): Likewise. (CHOOSE_f32x): Likewise. (CHOOSE_f64x): Likewise.
