Summary:
The build system was inconsistent in its naming conventions for
link flags. This patch changes all uses of LINKFLAGS to LINK_FLAGS,
for consistency with cmake's LINK_FLAGS property.
This patch should make it easier to search the source code for
uses of link flags, as well as providing the benefit of improved
style and consistency.

Although the CriticalSection itself doesnt need to be destroyed, there
may be debug data associated with it. Plug a possible small leak.

In some cases StructurizeCfg updates root node, but dominator info
remains unchanges, it causes crash when expensive checks are enabled.
To cope with this problem a new method was added to DominatorTreeBase
that allows adding new root nodes, it is called in StructurizeCfg to
put dominator tree in sync.
This change fixes PR27488.

This is the second part of a multi-part change to define additional
subcommands to the `llvm-xray` tool.
This change defines a conversion subcommand to take XRay log files, and
turns them from one format to another (binary or YAML). This currently
only supports the first version of the log file format, defined in the
compiler-rt runtime.
Depends on D21987.

This broke the following two bots:
lld-x86_64-win7: the test failed because a diff command is not available
on that bot. That's a configuration error of the bot and will be fixed soon.
llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast: "tar xf" failed on that
bot. I suspect that it is due to the maximum path limitation on Windows.
A build directory contains a buildbot name, so it's longer than usual on
that machine. On Windows, many filesystem operations fail if a path is
longer than 255 characters. I'll try to address that in another patch.

I think generated tar files are more compatible with old tar commands
because of r291494 and r291340, so I want to enable this test on buildbots.

When reserving copy relocation space for a shared symbol, scan the DSO's
program headers to see if the symbol is in a read-only segment. If so,
reserve space for that symbol in a new synthetic section named .bss.rel.ro
which will be covered by the relro program header.

This is in preparation for my next change, which will introduce a relro
nobits section. That requires that relro sections appear at the end of the
progbits part of the r/w segment so that the relro nobits section can appear
contiguously.
Because of the amount of churn required in the test suite, I'm making this
change separately.

We currently limit the length of TSan returned backtraces to 8, which is not necessary (and a bug, most likely). Let's remove this.

This method seems to have had a troubled life. This patch proposes that it
replaces the recently added helper function dumpSUIdentifier. This way, the
method can be used in other files using the SUnit class.

It was complaining about ambiguity between llvm::detail and
llvm::support::detail:
error C2872: 'detail': ambiguous symbol
note: could be 'llvm::detail'
note: or 'llvm::support::detail'
Standardize on llvm::support::detail to hide these symbols further.

Use constexpr recursion for alignof like we do for sizeof. Seems to work
with Clang and MSVC. Also, don't recurse twice to avoid slowdowns in
compilers that don't memoize constexpr results (Clang).

properly even when a non-type template parameter has a dependent type.
Previously, if a non-type template parameter was dependent, but not dependent
on an outer level of template parameter, we would not match the type of the
parameter. Under [temp.arg.template], we are supposed to check that the types
are equivalent, which means checking for syntactic equivalence in the dependent
case.
This also fixes some accepts-invalids when passing templates with auto-typed
non-type template parameters as template template arguments.

I unfortunately neglected to add it in r260540, but it has been
sitting in my working dir ever since. D'oh.
Modified to work with r290069, which made the CHECK patterns
themselves whitespace-sensitive as well, and remove the test added
then, as this tests both strict and non-strict modes.

If we split a filename into `Name` and `Prefix`, `Prefix` is at most
145 bytes. We had a bug that didn't split a path correctly. This bug
was pointed out by Rafael in the post commit review.
This patch adds a unit test for TarWriter to verify the fix.
