[PATCH] ARM: Remove VDUPf{d,q}f pseudo instructions

[James Molloy]

Hi,

 

The VDUPfdf and VDUPfqf pseudo instructions are broken - they do not
properly set implicit def/use flags. They're useless too, and can be
replaced by a pattern.

 

The attached patch removes them completely and adds test cases.

 

Please review!

 

Cheers,

 

James
