[llvm-reduce] Add reduction for aliases. This patch adds a new reduction pass that tries to remove aliases. It runs early, as most of those likely can be removed up-front in practice. This substantially improves llvm-reduce for IR generated by the swift compiler, which can generate a lot of aliases which lead to lots of invalid reductions.

[llvm-reduce] Reducing attributes Summary: This handles all three places where attributes could currently be - `GlobalVariable`, `Function` and `CallBase`. For last two, it correctly handles all three possible attribute locations (return value, arguments and function itself) There was a previous attempt at it D73853, which was committed in rGfc62b36a000681c01e993242b583c5ec4ab48a3c, but then reverted all the way back in rGb12176d2aafa0ccb2585aa218fc3b454ba84f2a9 due to some (osx?) test failures.

deltas/ReduceBasicBlocks.cpp
[Reduce] Try turning function definitions into declarations first, NFCI-ish ReduceFunctions could do it, but it also replaces *all* calls with undef, so if any of undef replacements makes reduction uninteresting, it won't work. ReduceBasicBlocks also could do it, but well, it may take many guesses for all the blocks of a function to happen to be out-of-chunk, which is not a very efficient way to go about it. So let's just do this first.

deltas/ReduceFunctions.cpp
[llvm-reduce] Refactor global variable delta pass The limitation of the current pass that it skips initializer-less GV's seems arbitrary, in all the reduced cases i (personally) looked at, the globals weren't needed, yet they were kept. So let's do two things: 1. allow reducing initializer-less globals 2. before reducing globals, reduce their initializers, much like we do function bodies

deltas/ReduceMetadata.cpp
deltas/ReduceOperandBundles.cpp
[llvm-reduce] Add reduction for special globals like llvm.used. This patch adds a reduction of 'special' globals that lead to further reductions (e.g. alias or regular globals reduction) being less efficient because there are special constraints on values referenced in those special globals. For example, values in @llvm.used and @llvm.compiler.used need to be named, so replacing all uses of an alias/global with undef or a different unnamed constant results in invalid IR.
