Drop old integer-gmp-0.5 from GHC source tree

This completes what c774b28f76ee4c220f7c1c9fd81585e0e3af0e8a (#9281)
started.  `integer-gmp-1.0` was added as an additional
`libraries/integer-gmp2` folder while retaining the ability to configure
GHC w/ the old `integer-gmp-0.5` to have a way back, and or the ability
to easily switch between old/new `integer-gmp` for benchmark/debugging
purposes.

This commit removes the old `libraries/integer-gmp` folder and moves
`libraries/integer-gmp2` into its place, while removing any mentions of
"gmp2" as well as the to support two different `integer-gmp` packages in
GHC's source-tree.

-Primitive Integer conversions to/from HsInt64 and HsWord64s.
-N.B. These are not primops!
-
-Instead of going the normal (boring) route of making the list
-of primitive operations even longer to cope with operations
-over 64-bit entities, we implement them instead 'out-of-line'.
-
-The primitive ops get their own routine (in C) that implements
-the operation, requiring the caller to _ccall_ out. This has
-performance implications of course, but we currently don't
-expect intensive use of either Int64 or Word64 types.
