Release Notes should just repeat first sentence from documentation.

Remove duplicated entry from Release Notes.

Summary:
 - JSON<->Obj interface is now ADL functions, so they play nicely with enums
 - recursive vector/map parsing and ObjectMapper moved to JSONExpr and tested
 - renamed (un)parse to (de)serialize, since text -> JSON is called parse
 - Protocol.cpp gets a bit shorter

Sorry for the giant patch, it's prety mechanical though

No test yet because the relevant rules are blocked on the atomic_load,
and atomic_store nodes.

Now that we have disabled the run-forever tests, and cleaned up the
intel 80-bit float based tests, we should be able to enable testing
compiler-rt for powerpc64.

The ELF spec says

Symbols with section index SHN_COMMON may appear only in relocatable
objects.

Currently lld can produce file that break that requirement.

unambiguously on one bit of code.  On macOS these
lines mapped to two distinct locations, and that
was artificially throwing off the test.

The 32-bit version is shorter to encode and the zext we emit for the promotion is likely going to be a 32-bit zero extend anyway.

This change adds support for the --only-keep option and the -j alias as well.
A common use case for these being used together is to dump a specific section's
data. Additionally the --keep option is added (GNU objcopy doesn't have this)
to avoid removing a bunch of things. This allows people to err on the side of
stripping aggressively and then to keep the specific bits that they need for
their application.

G_ATOMICRMW_* is generally legal on AArch64. The exception is G_ATOMICRMW_NAND.

G_ATOMIC_CMPXCHG_WITH_SUCCESS needs to be lowered to G_ATOMIC_CMPXCHG with an
external comparison.

Note that IRTranslator doesn't generate these instructions yet.

Modify add_sphinx_target() to include the project name alongside builder
in Sphinx doctree directory. This aims to avoid crashes due to race
conditions between multiple Sphinx instances running in parallel that
attempt to create or read that directory simultaneously.

This problem has originally been addressed in r283188. However, that
commit presumed that there will be only one target per builder being
run. However, r314863 introduced a second manpage target, reintroducing
the race condition.

Summary:
This check will find out improper initialization of NSError objects.

According to Apple developer document, we should always use factory method errorWithDomain:code:userInfo: to create new NSError objects instead of [NSError alloc] init]. Otherwise it will lead to a warning message during runtime in Xcode.

The corresponding information about NSError creation: https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/ErrorHandlingCocoa/CreateCustomizeNSError/CreateCustomizeNSError.html

Clang asserts on undeclared variables on the to or link clause in the declare
target directive. The patch is to properly diagnose the error.

If the inner teams region is not correct, it may cause an assertion when
processing outer target region. Patch fixes this problem.

When a linker script has "foo = bar" and bar is the result of a copy
relocation foo should point to the same location in .bss.

This is part of a growing evidence that copy relocations should be
implemented by using replaceSymbol to replace the SharedSymbol with a
Defined.

Perform a nested CMake invocation to avoid writing our own parser
for compiler versions when we are not testing the in-tree compiler.
Use the extracted information to mark a test as unsupported that
hangs with Clang prior to version 4.0.1 and restrict tests for
libomptarget to Clang version 6.0.0 and later.

As part of the unification of the debug format and the MIR format,
always use `printReg` to print all kinds of registers.

Updated the tests using '_' instead of '%noreg' until we decide which
one we want to be the default one.

In rare cases we can receive request to inject into completelly empty basic block. In the normal case 
all basic blocks contain at least terminator instruction, but it is possible that the only instruction is 
catchpad instruction which is not part of the instruction iterator. This case seems rare enough to not care
about it.
Submiting without review, since it seems almost NFC. I couldn't come up with any reasonable way to test this.

The test is about failing to hit breakpoints in global constructors in
