8de3a54f07 Revert @llvm.assume with operator bundles (r289755-r289757) 
This creates non-linear behavior in the inliner (see more details in
r289755's commit thread).

bffeba468d Remove the AssumptionCache 
After r289755, the AssumptionCache is no longer needed. Variables affected by
assumptions are now found by using the new operand-bundle-based scheme. This
new scheme is more computationally efficient, and also we need much less
code...

20b343c051 Consistently use FunctionAnalysisManager 
Besides a general consistently benefit, the extra layer of indirection
allows the mechanical part of https://reviews.llvm.org/D23256 that
requires touching every transformation and analysis to be factored out
cleanly.

Thanks to David for the suggestion.

fff81b23a8 [PM] Port LoopSimplify to the new pass manager. 
While here move simplifyLoop() function to the new header, as
suggested by Chandler in the review.

4e6b24ffcf Rename LoopSimplify.h to LoopUtils.h 
As discussed, LoopUtils.h is a better name.

fc32605ff3 Expose InsertPreheaderForLoop from LoopSimplify to other passes 
Other passes, PPC counter-loop formation for example, also need to add loop
preheaders outside of the regular loop simplification pass. This makes
InsertPreheaderForLoop a global function so that it can be used by other
passes.

No functionality change intended.
