[Hexagon] Create global std::map lazily.
...
This could of course be a simple binary search with no global state
involved at all if someone cares enough. Just don't make everyone
linking the hexagon backend pay for it on process startup and shutdown.

[Hexagon] Adding functionality for duplexing. Duplexing is a way to compress commonly used pairs of instructions in order to reduce code size. The test case duplex.ll normally would be 8 bytes, assign register to 0 and jump to link register. After duplexing this is only 4 bytes. This also tests the HexagonMCShuffler code path which is used to make sure duplexed instructions still follow slot requirements.
