In the context where we break one tok::greatergreater into two
tok::greater in order to correctly update the cached tokens; update the
CachedTokens with two tok::greater only if ParseGreaterThanInTemplateList
clients asks to consume the last token. Otherwise we only need to add
one because the second is already added later on, as a not yet cached token.

name lookup information have changed since deserialization. For a C++ modules
build, we do not need to re-emit the identifier into the serialized identifier
table if only the name lookup information has changed (and in all cases, we
don't need to re-emit the macro information if only the name lookup information
has changed).

Previously, it was easy to leave some Out<ELFT> fields uninitialized
because assignments to the fields are mixed with output section
instantiations. In this patch, I separate initializations from assignments
to improve readability.

Summary:
Allow hasName() to look through inline namespaces.
This will fix the interaction between some clang-tidy checks and libc++.
libc++ defines names in an inline namespace named std::<version_#>.
When we try to match a name using hasName("std::xxx") it fails to match and the clang-tidy check does not work.

LiveRangeEdit::eliminateDeadDef is used to remove dead define instructions
after rematerialization. To remove a VNI for a vreg from its LiveInterval,
LiveIntervals::removeVRegDefAt is used. However, after non-PHI VNIs are all
removed, PHI VNI are still left in the LiveInterval. Such unused vregs will
be kept in RegsToSpill[] at the end of InlineSpiller::reMaterializeAll and
spiller will allocate stackslot for them.
The fix is to get rid of unused reg by checking whether it has non-dbg
reference instead of whether it has non-empty interval.

This makes it less likely to clash with other stuff that might be linked
in by change, e.g. ncurses exposes an external function called simply
"echo", so linking ncurses statically into the binary explodes in funny
ways.

Because the Decl is explicitly passed as nullptr further up the call chain, it
is possible to invoke isa on a nullptr, which will assert. Guard against the
nullptr.
Take the opportunity to reuse the helper method rather than re-implementing this

In r255133 (reapplied r253126) we started to avoid redundant
recomputation of LCSSA after loop-unrolling. This patch moves one step
further in this direction - now we can avoid it for much wider range of
loops, as we start to look at IR and try to figure out if the
transformation actually breaks LCSSA phis or makes it necessary to
insert new ones.

CodeView, like most other debug formats, represents the live range of a
variable so that debuggers might print them out.
They use a variety of records to represent how a particular variable
might be available (in a register, in a frame pointer, etc.) along with
a set of ranges where this debug information is relevant.
However, the format only allows us to use ranges which are limited to a
maximum of 0xF000 in size. This means that we need to split our debug
information into chunks of 0xF000.
Because the layout of code is not known until *very* late, we must use a
new fragment to record the information we need until we can know
*exactly* what the range is.

Summary:
Passing the rematerialized values map to insertRematerializationStores by

Summary:
With this change generating clang order files using dtrace uses the following workflow:
cmake <whatever options you want>
ninja generate-order-file
ninja clang
This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.
CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.

When building a PCH with modules enabled this import would assert in the
ASTWriter and (if assertions were disabled) sometimes crash the compiler
that loaded the resulting PCH when trying to lookup the submodule ID.

Only single and double FP immediates are correctly printed by
MachineInstr::print() during debug output. Half float type goes to
APFloat::convertToDouble() and hits assertion it is not a double
semantics. This diff prints half machine operands correctly.
This cannot currently be hit by any in-tree target.
