Craig Topper 9202d5f8f1 [X86] Remove some intel syntax aliases on (v)cvtpd2(u)dq, (v)cvtpd2ps, (v)cvt(u)qq2ps. Add 'x' and'y' suffix aliases to masked version of the same in att syntax. 
The 128/256 bit version of these instructions require an 'x' or 'y' suffix to
disambiguate the memory form in att syntax.

We were allowing the same suffix in intel syntax, but it appears gas does not
do that.

gas does allow the 'x' and 'y' suffix on register and broadcast forms even
though its not needed. We were allowing it on unmasked register form, but not on
masked versions or on masked or unmasked broadcast form.

While there fix some test coverage holes so they can be extended with the 'x'
and 'y' suffix tests.

Craig Topper b8596e4d1d [X86] Cleanup 'x' and 'y' mnemonic suffixes for vcvtpd2dq/vcvttpd2dq/vcvtpd2ps and similar instructions. 
-Don't print the 'x' suffix for the 128-bit reg/mem VEX encoded instructions in Intel syntax. This is consistent with the EVEX versions.
-Don't print the 'y' suffix for the 256-bit reg/reg VEX encoded instructions in Intel or AT&T syntax. This is consistent with the EVEX versions.
-Allow the 'x' and 'y' suffixes to be used for the reg/mem forms when we're assembling using Intel syntax.
-Allow the 'x' and 'y' suffixes on the reg/reg EVEX encoded instructions in Intel or AT&T syntax. This is consistent with what VEX was already allowing.

This should fix at least some of PR28850.
