<pre>Normally mnemonics of the short and extended encoding differ by the suffix -
"_e32" and "_e64" respectively.
Some of VOP2/VOP3 instructions only have extended encoding.
In current implementation AMDGPUInstrPrinter appends "_e64" suffix to the
mnemonic if instruction description has SIInstrFlags::VOP3 flag set.
So we have a bunch of hacks around to suppress printing the "_e64" suffix for
the instructions that only have extended from.</pre>
