cdf9553102 [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.

084c4d499d [Hexagon] Disassembling, printing, and emitting instructions a whole-bundle at a time which is the semantic unit for Hexagon. Fixing tests to use the new format. Disabling tests in the direct object emission path for a followup patch.

0b619fcc8e [cleanup] Re-sort all the #include lines in LLVM using 
utils/sort_includes.py.

I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

10f65de3be Pass an ArrayRef to MCDisassembler::getInstruction. 
With this patch MCDisassembler::getInstruction takes an ArrayRef<uint8_t>
instead of a MemoryObject.

Even on X86 there is a maximum size an instruction can have. Given
that, it seems way simpler and more efficient to just pass an ArrayRef
to the disassembler instead of a MemoryObject and have it do a virtual
call every time it wants some extra bytes.

8cb53479d4 Misc style fixes. NFC. 
This fixes a few cases of:

* Wrong variable name style.
* Lines longer than 80 columns.
* Repeated names in comments.
* clang-format of the above.

This make the next patch a lot easier to read.
