Summary:
Avoid special case for FP, LR CFI emission and just allow general
AArch64FrameLowering::emitCalleeSavedFrameMoves() to handle them. Also,
stop recalculating the stack offsets in emitCalleeSavedFrameMoves()
since we can just reuse the previously calculated offset stored in the
MachineFrameInfo.

The generated dedicated subregion exit block was assumed to have the same
dominance relation as the original exit block. This is incorrect if the exit
block receives other edges than only from the subregion, which results in that
e.g. the subregion's entry block does not dominate the exit block.

From now on we bail only if a non-trivial alias group contains a non-affine
access, not when we discover aliasing and non-affine accesses are allowed.

Most address represented in lldb as section plus offset and handling of
absolute addresses is problematic in several location because of lack
of necessary information (e.g. Target) or because of performance issues.
This CL change the way ObjectFileELF handle the absolute symbols with
creating a pseudo section for each symbol. With this change all existing
code designed to work with addresses in the form of section plus offset
will work with absolute symbols as well.

Resubmit with index problem fixed. Verified with valgrind.
Prepare to support DPP encodings.
For DPP encodings, we want row_mask/bank_mask/bound_ctrl to be optional operands.
However this means that when parsing instruction which has no mnemonic prefix,
we cannot add both default values for VOP3 and for DPP optional operands
to OperandVector - neither instructions would match. So add default values
for optional operands to MCInst during conversion instead.
Mark more operands as IsOptional = 1 in .td files.
Do not add default values for optional operands to OperandVector in AMDGPUAsmParser.
Add default values for optional operands during conversion using new helper addOptionalImmOperand.
Change to cvtVOP3_2_mod to check instruction flag instead of presence of modifiers. In the future, cvtVOP3* functions can be combined into one.
Separate cvtFlat and cvtFlatAtomic.
Fix CNDMASK_B32 definition to have no modifiers.

the testing more more explicit.
This will currently fail on platforms without support for getTypeName.
While an assert failure seems too harsh, I'm hoping we're OK with the
regression test failure, and I'd like to find out about what platforms
actually exist in this state if there are any so we can get
implementations in place for them.
But if we just can't fix all the host compilers to have a reasonably
portable variant of getTypeName and are worried about xfailing this test
on those platforms, I can add the horrible regular expression magic to
make the tests support "unknown" here as well.

This creates the new-style LoopPassManager and wires it up with dummy
and print passes.
This version doesn't support modifying the loop nest at all. It will
be far easier to discuss and evaluate the approaches to that with this
in place so that the boilerplate is out of the way.

The assert isn't correct since TypeLoc::ObjCObjectTypeLoc doesn't
indicate whether the type is a dependent type. The function returns
false for a type like "<SomeProtocol>" which is a synonym for
"id<SomeProtocol>".

ICC on Windows where it mimics MSVC's behavior and supports __FUNCSIG__.

OpenMP 4.5 allows to privatize non-static member decls in non-static
member functions. Patch captures such decls by reference in general (for
bitfields, by value) and then operates with this capture. For bitfields,
at the end of codegen for lastprivates original bitfield is updated with the value of captured copy.

(within the DeclRefExpr Node) when creating AST nodes that reference specializations of static data member templates. While we pass the template args through for all non-instance members, they should only be relevant (i.e. non-null) for variable template ids (assertion added for that assumption)
Also preserve the FoundDecl that refers to the canonical Decl (the primary VarTemplateDecl for a variable template specialization) that we are referencing in our DeclRefExpr. Not sure why this was not being done for non-variable template-ids.
No functionality change - so no tests added.
Thanks to Richard Smith for drawing my attention to this!

This commit does two related thing. At first, it enumerates supported
absolute MIPS relocations in the `MipsTargetInfo<ELFT>::isRelRelative`
method. In that case the code is shorter and the case switch does not
tend to grow. At second, it prevents R_MIPS_COPY and PLT creation for
relative relocations. For almost all relative MIPS relocations like
R_MIPS_PC19_S2, R_MIPS_PCHI16 etc it does not have a sence. The only
exception is R_MIPS_PC32. GNU linker creates a copy relocation or PLT
entry for it. But I could not find any real test case uses R_MIPS_PC32
with DSO defined symbol as a target. So for now I prefer to skip this
case to simplify the LLD code.
