    x86: Don't pad .tfloat directive output

    .tfloat output should always be 10 bytes without padding, independent
    of psABIs.  In glibc, x86 assembly codes expect 10-byte .tfloat output.
    This also reduces .ds.x output and .tfloat output with hex input from
    12 bytes to 10 bytes to match .tfloat output.

            PR gas/28230
            * NEWS: Mention changes of .ds.x output and .tfloat output with
            hex input.
            * config/tc-i386.c (x86_tfloat_pad): Removed.
            * config/tc-i386.h (X_PRECISION_PAD): Changed to 0.
            (x86_tfloat_pad): Removed.
            * testsuite/gas/i386/fp.s: If NO_TFLOAT_PADDING isn't defined,
            add explicit paddings after .tfloat, .ds.x, .dc.x and .dcb.x
            directives.
            * testsuite/gas/i386/i386.exp (ASFLAGS): Append
            "--defsym NO_TFLOAT_PADDING=1" when running the fp test.
