Delete compiler/MachDeps.h

This was accidentally added back in
28334b475a109bdeb8d53d58c48adb1690e2c9b4 after it is was no longer
needed by the compiler proper in
20956e5784fe43781d156dd7ab02f0bff4ab41fb.

- * NB: THIS FILE IS INCLUDED IN HASKELL SOURCE!

-/* Don't allow stage1 (cross-)compiler embed assumptions about target
- * platform. When ghc-stage1 is being built by ghc-stage0 is should not
- * refer to target defines. A few past examples:
- *  - https://gitlab.haskell.org/ghc/ghc/issues/13491
- *  - https://phabricator.haskell.org/D3122
- *  - https://phabricator.haskell.org/D3405
- *
- * In those cases code change assumed target defines like SIZEOF_HSINT
- * are applied to host platform, not target platform.
- *
- * So what should be used instead in GHC_STAGE=1?
- *
- * To get host's equivalent of SIZEOF_HSINT you can use Bits instances:
- *    Data.Bits.finiteBitSize (0 :: Int)
- *
- * To get target's values it is preferred to use runtime target
- * configuration from 'targetPlatform :: DynFlags -> Platform'
- * record.
- *
- * Hence we hide these macros from GHC_STAGE=1

-/* Sizes of C types come from here... */
-#include "ghcautoconf.h"
-
-/* Sizes of Haskell types follow.  These sizes correspond to:
- *   - the number of bytes in the primitive type (eg. Int#)
- *   - the number of bytes in the external representation (eg. HsInt)
- *   - the scale offset used by writeFooOffAddr#
- *
- * In the heap, the type may take up more space: eg. SIZEOF_INT8 == 1,
- * but it takes up SIZEOF_HSWORD (4 or 8) bytes in the heap.
