Use CGLoopInfo to emit metadata for loop hint pragmas.
When ‘#pragma clang loop vectorize(assume_safety)’ was specified on a loop other loop hints were lost. The problem is that CGLoopInfo attaches metadata differently than EmitCondBrHints in CGStmt. For do-loops CGLoopInfo attaches metadata to the br in the body block and for while and for loops, the inc block. EmitCondBrHints on the other hand always attaches data to the br in the cond block. When specifying assume_safety CGLoopInfo emits an empty llvm.loop metadata shadowing the metadata in the cond block. Loop transformations like rotate and unswitch would then eliminate the cond block and its non-empty metadata.
This patch unifies both approaches for adding metadata and modifies the existing safety tests to include non-assume_safety loop hints.

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.

[MS Extensions] Remove support for the i128 integer literal suffix
There is currently no support in MSVC for using i128 as an integer
literal suffix. In fact, there appears to be no evidence that they have
ever supported this feature in any of their compilers. This was an over
generalization of their actual feature and is a nasty source of bugs.
Why is it a source of bugs? Because most code in clang expects that
evaluation of an integer constant expression won't give them something
that 'long long' can't represent. Instead of providing a meaningful
feature, i128 gives us cute ways of exploding the compiler.

[llvm-dwarfump] Don't rely on global state, part 3.
Some tools used to rely on a global static variable to keep track of the
return value for main(). I changed llvm-cxxdump to use exit(1)
and Rafael shortly after did the same with llvm-readobj. This is
(yet) another step towards the goal.

[LAA] Begin moving the logic of generating checks out of addRuntimeCheck
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).
