b61054ff8f Stop APInt::shl from generating llvm.trap
APInt::shl generated llvm.trap to guard against shifts greater than bit-width.
This was already checked with an assert, and there was a special case for
shifts equal to bit-width. Modify this check to catch shifts greater than or
equal to bit-width, so llvm.trap isn't generated.

8999f4777b LoopSimplify: Preserve DependenceAnalysis.
This is currently true, but may change when DA grows more aggressive caching.
Without this setting it's impossible to use DA from a LoopPass because DA is a
function pass and cannot be properly scheduled in between LoopPasses. The
LoopManager reacts to this with an infinite loop which made this really annoying
to debug.

b2b2273ef4 Fix SCEV cache invalidation in LCSSA and LoopSimplify.
The LoopSimplify bug is pretty harmless because the loop goes from unanalyzable
to analyzable but the LCSSA bug is very nasty. It only comes into play with a
specific order of the LoopPassManager worklist and can cause actual
miscompilations, when a SCEV refers to a value that has been replaced with PHI
node. SCEVExpander may then insert code into the wrong place, either violating
domination or randomly miscompiling stuff.

Comes with an extensive test case reduced from the test-suite with
bugpoint+SCEVValidator.

ff18310274 Add a basic verifier for SCEV's backedge taken counts.
Enabled with -verify-scev. This could be extended significantly but hopefully
catches the common cases now. Note that it's not enabled by default in any
configuration because the way it tries to distinguish SCEVs is still fragile and
may produce false positives. Also the test-suite isn't clean yet, one example
is that it fails if a pass drops an NSW bit but it's still present in SCEV's
cached. Cleaning up all those cases will take some time.

edf5e9a1d5 PowerPC: Fix for rldcl/rldicl/rldicr MC emission
This patch fixes the rldcl/rldicl/rldicr instruction emission. The issue is
the MDForm_1 instruction defines the PowerISA MB field from 'rldicl'
with the name MBE, but RLDCL/RLDICL/RLDICR definition uses as 'MB'.

It end up by generatint the 'rldicl' enconding at 
'lib/Target/PowerPC/PPCGenMCCodeEmitter.inc' to use the fourth argument as the
third. The patch changes it by adjusting to use the fourth argument as
intended.

Fixes PR14180.

4734fe19f6 Hoist out some work done inside a loop doing a linear scan over all
instructions in a block. GetUnderlyingObject is more expensive than it looks as
it can, for instance, call SimplifyInstruction.

This might have some behavioural changes in odd corner cases, but only because
of some strange artefacts of the original implementation. If you were relying
on those, we can fix that by replacing this with a smarter algorithm. Change
passes the existing tests.

fffb72470d libLTO has a bug in that it will keep every symbol if none is needed. We used
to hack around this in the gold plugin by deleting a module if no symbol was
needed. Unfortunately, the hack is wrong in the case of o module having no
visible symbols but still having side effects via static constructors.

The bug will have to be fixed in libLTO itself.
