LLVM previously used `DW_CFA_def_cfa` instruction in .eh_frame to set
the register and offset for current CFA rule. We change it to
`DW_CFA_def_cfa_register` which is the same one used by GAS that only
changes the register but keeping the old offset.
Patch by Mirko Brkusanin.

Pass '--mode=compile' to fix compiler-full-path.test failure on NetBSD
buildbot (apparently due to lack of 'link' executable).
Fixes r360355. Acked by Pavel Labath.

Summary:
This is the final phase of the refactoring towards using llvm::Expected
and llvm::Error in the ASTImporter API.
This involves the following:
- remove old Import functions which returned with a pointer,
- use the Import_New functions (which return with Err or Expected) everywhere
and handle their return value
- rename Import_New functions to Import
This affects both Clang and LLDB.

This reduces the number of parameters we need to pass in and they seem a
natural fit in LoopVectorizationCostModel. Also simplifies things for
D59995.
As a follow up refactoring, we could only expose a expose a
shouldUseVectorIntrinsic() helper in LoopVectorizationCostModel, instead
of calling getVectorCallCost/getVectorIntrinsicCost in
InnerLoopVectorizer/VPRecipeBuilder.

This adds a specific error message to clarify that lldb requires libcxx when
built together with clang on macOS. In addition, the lldb building docs are also
updated.

The class has been converted to use DWARFUnit, but a number of uses of
the words compile unit remained. This removes all such references
Get/SetCompileUnit becomes Get/SetUnit, and m_cu becomes m_unit.

They encode the same way, but OR32mi8Locked sets hasUnmodeledSideEffects set
which should be stronger than the mayLoad/mayStore on LOCK_OR32mi8. I think
this makes sense since we are using it as a fence.
This also seems to hide the operation from the speculative load hardening pass
so I've reverted r360511.

This reverts commit b5a8abd57f23e2f621d5ceb0f64f1bb8f9579c3f. This
should not be needed as the lldb-server tool will add
`LLDB_CAN_USE_LLDB_SERVER` which will never be set to true on Windows.

The 3-field form was introduced by D3499 in 2014 and the legacy 2-field
form was planned to be removed in LLVM 4.0
For the textual format, this patch migrates the existing 2-field form to
use the 3-field form and deletes the compatibility code.
test/Verifier/global-ctors-2.ll checks we have a friendly error message.
For bitcode, lib/IR/AutoUpgrade UpgradeGlobalVariables will upgrade the
2-field form (add i8* null as the third field).

Summary:
I don't think there's a good reason for this behavior to be considered
ObjC-specific. We can generalize this.

This was the portion split off D58632 so that it could follow the redzone API cleanup. Note that I changed the offset preferred from -8 to -64. The difference should be very minor, but I thought it might help address one concern which had been previously raised.

The code is currently using the ambiguous instruction
"sub sp, sp, w9, lsl #4". The ARM reference manual says this isn't
valid, and it's not clear whether it's supposed to mean uxtw or uxtx.
It doesn't matter which instruction we use here, since the high
bits of the operand are zero anyway, so I arbitrarily choose uxtw, to
preserve the register name.
See https://reviews.llvm.org/D60840 for the LLVM patch.
