Speed up iteration of CodeView record streams.
There's some abstraction overhead in the underlying
mechanisms that were being used, and it was leading to an
abundance of small but not-free copies being made. This
showed up on a profile. Eliminating this and going back to
a low-level byte-based implementation speeds up lld with
/DEBUG between 10 and 15%.

GlobalISel: Make MachineCSE runnable in the middle of the GlobalISel
Right now, it is not possible to run MachineCSE in the middle of the
GlobalISel pipeline. Being able to run generic optimizations between the
core passes of GlobalISel was one of the goals of the new ISel framework.
This is the first attempt to do it.
The problem is that MachineCSE pass assumes all register operands have a
register class, which, in GlobalISel context, won't be true until after the
InstructionSelect pass. The reason for this behaviour is that before
replacing one virtual register with another, MachineCSE pass (and most of
the other optimization machine passes) must check if the virtual registers'
constraints have a (sufficiently large) intersection, and constrain the
resulting register appropriately if such intersection exists.
GlobalISel extends the representation of such constraints from just a
register class to a triple (low-level type, register bank, register
class).
This commit adds MachineRegisterInfo::constrainRegAttrs method that extends
MachineRegisterInfo::constrainRegClass to such a triple.
The idea is that going forward we should use:
- RegisterBankInfo::constrainGenericRegister within GlobalISel's
InstructionSelect pass
- MachineRegisterInfo::constrainRegClass within SelectionDAG ISel
- MachineRegisterInfo::constrainRegAttrs everywhere else regardless
the target and instruction selector it uses.

[Attributes] Fix crash when attempting to remove alignment from an attribute list/set
Summary:
Discovered while working on a patch to move alignment in
@llvm.memcpy/move/set from an arg into parameter attributes.
The current implementations of AttributeSet::removeAttribute() and
AttributeList::removeAttribute crash when attempting to remove the
alignment attribute. Currently, these implementations add the
to-be-removed attributes to an AttrBuilder and then remove
the builder from the list/set. Alignment is special in that it
must be added to a builder with an integer value for the alignment;
attempts to add alignment to a builder without a value is an error.
This change fixes the removeAttribute implementations for AttributeSet and
AttributeList to make them able to remove the alignment, and other similar,
attributes.

[X86] When legalizing (v64i1 select i8, v64i1, v64i1) make sure not to introduce bitcasts to i64 in 32-bit mode
We legalize selects of masks with scalar conditions using a bitcast to an integer type. But if we are in 32-bit mode we can't convert v64i1 to i64. So instead split the v64i1 to v32i1 and concat it back together. Each half will then be legalized by bitcasting to i32 which is fine.
The test case is a little indirect. If we have the v64i1 select in IR it will get legalized by legalize vector ops which has a run of type legalization after it. That type legalization run is able to fix this i64 bitcast. So in order to avoid that we need a build_vector of a splat which legalize vector ops will ignore. Legalize DAG will then turn that into a select via LowerBUILD_VECTORvXi1. And the select will get legalized. In this case there is no type legalizer run to cleanup the bitcast.
This fixes pr35972.

Don't emit apple accelerator tables on non-darwin targets
Summary:
Currently -glldb turns on emission of apple tables on all targets, but
lldb is only really capable of consuming them on darwin. Furthermore,
making lldb consume these tables is not straight-forward because of the
differences in how the debug info is distributed on darwin vs. elf
targets.
The darwin debug model assumes that the debug info (along with
accelerator tables) will either remain in the .o files or it will be
linked into a dsym bundle by a linker that knows how to merge these
tables. In the elf world, all present linkers will simply concatenate
these accelerator tables into the shared object. Since the tables are
not self-terminating, this renders the tables unusable, as the debugger
cannot pry the individual tables apart anymore.
It might theoretically be possible to make the tables work with split
dwarf, as that is somewhat similar to the apple .o model, but
unfortunately right now the combination of -glldb and -gsplit-dwarf
produces broken object files.
Until these issues are resolved there is no point in emitting the apple
tables for these targets. At best, it wastes space; at worst, it breaks
compilation and prevents the user from getting other benefits of -glldb.

We can't trivially make the same change for ARM, because one of the
values it returns is the bitwise-or of two `ARM::ArchExtKind`s.

Fix pretty printing the unspecified param of a variadic function
Summary:
- Fix a bug in PrettyBuiltinDumper that returns "void" as the name for
an unspecified builtin type. Since the unspecified param of a variadic
function is considered a builtin of unspecified type in PDBs, we set
"..." for its name.
- Provide a method to determine if a PDBSymbolFunc is variadic in
PrettyFunctionDumper since PDBSymbolFunc::getArgument() doesn't return the
last unspecified-type param.
- Add a pretty-func-dumper.test to test pretty dumping of variadic
functions.

When "xer" is specified as clobbered register in inline assembler, clang can accept it, but llvm simply ignore it when lowered to machine instructions. It may cause problems later in scheduler.
This patch adds a new register XER aliased to CARRY, and adds it to register class CARRYRC. Now PPCTargetLowering::getRegForInlineAsmConstraint can return correct register number for inline asm constraint "{xer}", and scheduler behave correctly.
