Since there are no changes to the metadata do we need this? Can make the V5 one 
be V5 and V6.

If you could add 0x04f as "reserved" in this (or other, separate) PR, it would 
be great.

e.g. EF_AMDGPU_MACH_AMDGCN_RESERVED_0X4D

@arsenm Hi, can you take a look - especially on the testing? I don't know if 
this is tested well enough

Note: testing is a bit light for now, I'd like to add more tests, but I'm not 
sure what kind of tests are worth adding.
I could just add a generic target run line wherever gfx9/10/11 run lines are 
present, but that seems a bit overkill? I'd need to change half the tests we 
have or more.
