4df83ed159 Implement bottom-up fast-isel. This has the advantage of not requiring 
a separate DCE pass over MachineInstrs.

f423a69839 Add X86FastISel support for return statements. This entails refactoring 
a bunch of stuff, to allow the target-independent calling convention
logic to be employed.

eabaed26c3 Give FunctionLoweringInfo an MBB member, avoiding the need to pass it 
around everywhere, and also give it an InsertPt member, to enable isel
to operate at an arbitrary position within a block, rather than just
appending to a block.

a4160c3434 Simplify FastISel's constructor by giving it a FunctionLoweringInfo 
instance, rather than pointers to all of FunctionLoweringInfo's
members.

This eliminates an NDEBUG ABI sensitivity.

9e86f4364b Remove interprocedural-basic-aa and associated code. The AliasAnalysis 
interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.
It's not currently worthwhile to add a new interface for this new
concept.

Document that AliasAnalysis doesn't support cross-function queries.

8246adc1f0 Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts" 
builds to "Release".  The default build is unchanged (optimization on,
assertions on), however it is now called Release+Asserts.  The intent
is that future LLVM releases released via llvm.org will be Release builds
in the new sense, i.e. will have assertions disabled (currently they have
assertions enabled, for a more than 20% slowdown).  This will bring them
in line with MacOS releases, which ship with assertions disabled.  It also
means that "Release" now means the same things in make and cmake builds:
cmake already disables assertions for "Release" builds AFAICS.

c66e150b2c By default, the eh.sjlj.setjmp/longjmp intrinsics should just do nothing rather 
than assuming a target will custom lower them. Targets which do so should
exlicitly mark them as having custom lowerings. PR7454.
