<rdar://problem/10063437>

Reviewed by Gavin Barraclough and Oliver Hunt.

Ported the LLInt, which previously only worked on 32-bit, to 64-bit. This
patch moves a fair bit of code from LowLevelInterpreter32_64.asm to the common
file, LowLevelInterpreter.asm. About 1/3 of the LLInt did not have to be
specialized for value representation.

Also made some minor changes to offlineasm and the slow-paths.
