Reduce number of constants in __finite* (bug 15384).
Bug 15384 notes that in __finite, two different constants are used that could be the same constant (the result only depends on the exponent of the floating-point representation), and that using the same constant is better for architectures where constants need loading from a constant pool. This patch implements that change. Tested for x86_64, mips64 and powerpc. [BZ #15384] * sysdeps/ieee754/dbl-64/s_finite.c (FINITE): Use same constant as bit-mask as in subtraction. * sysdeps/ieee754/dbl-64/wordsize-64/s_finite.c (__finite): Likewise. * sysdeps/ieee754/flt-32/s_finitef.c (FINITEF): Likewise. * sysdeps/ieee754/ldbl-128/s_finitel.c (__finitel): Likewise. * sysdeps/ieee754/ldbl-128ibm/s_finitel.c (__finitel): Likewise.
