Missing document about RTS's -T option

[shelarcy]

Users Guide doesn't describe RTS's -T option except 7.4.1's release note.

• http://www.haskell.org/ghc/dist/stable/docs/html/users_guide/runtime-control.html#rts-options-gc
• http://www.haskell.org/ghc/dist/stable/docs/html/users_guide/release-7-4-1.html#id525874

Please add document about RTS's -T option in "Running a compiled program" section.
