Krzysztof Parzyszek becf0a362a Revert "[Hexagon] Address ASAN and UBSAN failures after r294226" 
This reverts commit r294256. It seems to be causing more problems instead
of solving them.

Justin Bogner b03fd12cef Replace "fallthrough" comments with LLVM_FALLTHROUGH 
This is a mechanical change of comments in switches like fallthrough,
fall-through, or fall-thru to use the LLVM_FALLTHROUGH macro instead.

Justin Bogner aa315fbb4c Hexagon: Paper over the undefined behaviour introduced by r238692 
This stops shifting a 32-bit value by such absurd amounts as 96 and
120. We do this by dropping a call to the function that was doing this
entirely, which rather surprisingly doesn't break *any* tests.

I've also added an assert in the misbehaving function to prove that
it's no longer being called with completely invalid arguments.

This change looks pretty bogus and we should probably be reverting
r238692 instead, but this is hard to do with the number of follow ups
that have happened since. It can't be any worse than the undefined
behaviour that was happening before though.
