Refactor: delete most of the module FastTypes
This reverses some of the work done in #1405, and goes back to the
assumption that the bootstrap compiler understands GHC-haskell.
In particular:
* use MagicHash instead of _ILIT and _CLIT
* pattern matching on I# if possible, instead of using iUnbox
unnecessarily
* use Int#/Char#/Addr# instead of the following type synonyms:
- type FastInt = Int#
- type FastChar = Char#
- type FastPtr a = Addr#
* inline the following functions:
- iBox = I#
- cBox = C#
- fastChr = chr#
- fastOrd = ord#
- eqFastChar = eqChar#
- shiftLFastInt = uncheckedIShiftL#
- shiftR_FastInt = uncheckedIShiftRL#
- shiftRLFastInt = uncheckedIShiftRL#
* delete the following unused functions:
- minFastInt
- maxFastInt
- uncheckedIShiftRA#
- castFastPtr
- panicDocFastInt and pprPanicFastInt
* rename panicFastInt back to panic#
These functions remain, since they actually do something:
* iUnbox
* bitAndFastInt
* bitOrFastInt
