 Implement -dword-hex-literals

 Provide flag for showing showing Word# and Word64# as hexadecimal when
 dumping GHC core.  The only affects Word, not Int, and it prefixes the
 hexadecimal with enough zeroes to make the total character count a power
 of two. For example:

 - 0x0C0C instead of 0xC0C
 - 0x00BA00BA instead of 0xBA00BA

 This also affects the presentation of Word# and Word64# in GHC's error
 messages. It is not expected that the flag will be used for this, but
 it is a side-effect worth noting.

 Test Plan: none
