Fix `llvm-config` to emit the linker flag for the combined shared object built by autoconfig/make instead of the individual components.

Summary:
When LLVM is configured to build shared libraries, CMake builds each component as it's own shared object, while autoconfig/make builds them statically and then links them all together to create a single shared object. This change adds compile time config flags to `llvm-config` so it can know whether LLVM's components are separated or not and act accordingly.

This fixes `llvm-config` instead of fixing the makefiles to behave like CMake because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.

This change only affects `llvm-config` from builds that use autoconfig/make.

[TTI/CostModel] improve TTI::getGEPCost and use it in CostModel::getInstructionCost

Summary:
This patch updates TargetTransformInfoImplCRTPBase::getGEPCost to consider
addressing modes. It now returns TCC_Free when the GEP can be completely folded
to an addresing mode.

I started this patch as I refactored SLSR. Function isGEPFoldable looks common
and is indeed used by some WIP of mine. So I extracted that logic to getGEPCost.

Furthermore, I noticed getGEPCost wasn't directly tested anywhere. The best
testing bed seems CostModel, but its getInstructionCost method invokes
getAddressComputationCost for GEPs which provides very coarse estimation. So
this patch also makes getInstructionCost call the updated getGEPCost for GEPs.
This change inevitably breaks some tests because the cost model changes, but
nothing looks seriously wrong -- if we believe the new cost model is the right
way to go, these tests should be updated.

This patch is not perfect yet -- the comments in some tests need to be updated.
I want to know whether this is a right approach before fixing those details.

Summary:
The goal is to start moving us closer to the model where
RuntimePointerChecking will compute and store the checks.  Then a client
can filter the check according to its requirements and then use the
filtered list of checks with addRuntimeCheck.

Before the patch, this is all done in addRuntimeCheck.  So the patch
starts to split up addRuntimeCheck while providing the old API under
what's more or less a wrapper now.

The new underlying addRuntimeCheck takes a collection of checks now,
expands the code for the bounds then generates the code for the checks.

I am not completely happy with making expandBounds static because now it
needs so many explicit arguments but I don't want to make the type
PointerBounds part of LAI.  This should get fixed when addRuntimeCheck
is moved to LoopVersioning where it really belongs, IMO.

Audited the assembly diff of the testsuite (including externals).  There
is a tiny bit of assembly churn that is due to the different order the
code for the bounds is expanded now
(MultiSource/Benchmarks/Prolangs-C/bison/conflicts.s and with LoopDist
on 456.hmmer/fast_algorithms.s).

[ARM] - Fix lowering of shufflevectors in AArch32

Some shufflevectors are currently being incorrectly lowered in the AArch32
backend as the existing checks for detecting the NEON operations from the
shufflevector instruction expects the shuffle mask and the vector operands to be
of the same length.

This is not always the case as the mask may be twice as long as the operand;
here only the lower half of the shufflemask gets checked, so provided the lower
half of the shufflemask looks like a vector transpose (or even is just all -1
for undef) then the intrinsics may get incorrectly lowered into a vector
transpose (VTRN) instruction.

This patch fixes this by accommodating for both cases and adds regression tests.
