x86: Allow integer conversion without suffix in AT&T syntax

According to gas manual, suffix in instruction mnemonics isn't always
required:

When there is no sizing suffix and no (suitable) register operands to
deduce the size of memory operands, with a few exceptions and where long
operand size is possible in the first place, operand size will default
to long in 32- and 64-bit modes.

This includes cvtsi2sd, cvtsi2ss, vcvtsi2sd, vcvtsi2ss, vcvtusi2sd and
vcvtusi2ss.  Since they are used in GCC 8 and older GCC releases, they
must be allowed without suffix in AT&T syntax.
