Continue to clean up legacy code's memory allocation practices. Changes include -- Several classes were holding reference to a vISA memory manager but not performing any allocation. Remove such references and any resulting dead allocators. -- Have each class (RA, SWSB, DebugInfo, etc.) create its own memory manager instaed of passing the kernel's memory manager in. This should reduce vISA memory footprint as such class object's allocations will now be freed at the end of their lifetime. -- Avoid creating variable names in non-debug build for the spill manager, as the variable names are only used when dumping IR. -- Give unique names for each class's memory manager to make searching their uses easier.
