LTO: document LTO_API_VERSION for each API
Adding a doxygen comment for each bit of API to indicate at which LTO_API_VERSION each was available, manually gleaned from successive git-blames. A few notes: - LTO_API_VERSION was set to 3 at its introduction. - I've indicated all the API introduced before LTO_API_VERSION was around as available "prior to LTO_API_VERSION=3". - A number of API changes neglected to bump LTO_API_VERSION. These I've indicated as available at the *next* bump of LTO_API_VERSION. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199429 91177308-0d34-0410-b5e6-96231b3b80d8
