Remove use of assignment to multiple struct fields using .fieldname syntax.
This doesn't work with gcc 4.8 and earlier. Replace with elementwise field assignments.

Several tests wouldn't pass when executed on an armv7a_pc_linux triple
due to the non-default arm_aapcs calling convention produced on the
function definitions in the IR output. Account for this with the
application of a little regex.

Fix OMPT support for barriers so that state changes occur even if OMPT_TRACE turned off.
These state changes are needed by performance tools that use callbacks for either
ompt_event_wait_barrier_begin or ompt_event_wait_barrier_end. Change ifdef flag to OMPT_BLAME
for callbacks ompt_event_wait_barrier_begin or ompt_event_wait_barrier_end rather than
OMPT_TRACE -- they were misclassified. Without this patch, when the runtime is compiled with
LIBOMP_OMPT_SUPPORT=true, LIBOMP_OMPT_BLAME=true, and LIBOMP_OMPT_TRACE=false, and a callback
is registered for either ompt_event_wait_barrier_begin or ompt_event_wait_barrier_end, then an
assertion will trip. Fix the scoping of one OMPT_TRACE ifdef, which should not have surrounded
an update of an OMPT state. Add a missing initialization of an OMPT task id for an implicit task.

Make sure to remove the unique lock file, which is what the .lock
symlink points to, if there is a signal while the lock is held. This
will release the lock, since the symlink will point to nothing (already
tested in unit tests). For good measure, also clean up the unique lock
file if there is an error or signal before the lock is acquired.
I will add a clang test.

This commit implements serialization of the register mask machine
operands. This commit serializes only the call preserved register
masks that are defined by a target, it doesn't serialize arbitrary
register masks.
This commit also extends the TargetRegisterInfo class and TableGen so that
the users of TRI can get the list of all the call preserved register masks and
their names.

struct sigaction was not initialized. As the result if SA_RESETHAND is set in sa_flags, then the handler is reset after first invocation leading to crash.
Initialize struct sigaction to zero.

The random module in Python 2.7.8 and later leaks /dev/[u]random into
children. The test is expected to fail, not be flakey.
This will be fixed in Python 2.7.10 for some operating systems, but not
all e.g. OS X 10.4.

This is very preliminary support, but it seems to work for the most common case.
When observing more/different test cases, we can work on generalizing this.

Compilers recognize "main" function and don't mangle its name.
But if you use a different function as a user-defined entry name,
and if you didn't define that function with extern C, your entry
point function name is mangled. And the linker has to be able to
find that. This is relatively rare but can happen.

The expressions we delinearize do not necessarily have to have a SCEVAddRecExpr
at the outermost level. At this moment, the additional flexibility is not
exploited in LLVM itself, but in Polly we will soon soonish use this
functionality. For LLVM, this change should not affect existing functionality
(which is covered by test/Analysis/Delinearization/)

This moves the error checking for string tables to getStringTable which returns
an ErrorOr<StringRef>.
This improves error checking, makes it uniform across all string tables and
makes it possible to check them once instead of once per name.

The new suppression type is called "race_top" and is matched only against top frame in report stacks.
This is required for situations when we want to suppress a race in a "thread pool" or "event loop" implementation.
If we simply use "race:ThreadPool::Execute" suppression, that can suppress everything in the program.

Most build system depends on existence or time stamp of a file.
This patch is to create an empty file for /pdb:<filename> option
just to satisfy some build rules.

Summary:
Current default is 10 minutes, which causes the test suite to run very long in
case of test timeouts. On local linux, each test completes in under 90 seconds in the
slowest configuration (debug build of lldb, using debug clang to build
inferiors). I am changing the default to 4m on local targets, while retaining
the 10m timeout for remote ones.

It was a fairly broken concept for an ELF only class.
An ELF file can have two symbol tables, but they have exactly the same
format. There is no concept of a dynamic or a static symbol. Storing this
on the iterator also makes us do more work per symbol than necessary. To fetch
a name we would:
* Find if we had a static or a dynamic symbol.
* Look at the corresponding symbol table and find the string table section.
* Look at the string table section to fetch its contents.
* Compute the name as a substring of the string table.
All but the last step can be done per symbol table instead of per symbol. This
is a step in that direction.

are currently not present in llvm/clang.This patch adds the options:
'neon-fp16', 'vfpv3-fp16', 'vfpv3-d16-fp16', 'vfpv3xd' and 'vfpv3xd-fp16.
These are related to half-precision floating-point and single precision.

Summary:
Some old linux versions do not have process_vm_readv function defined. Even older versions do not
have even the __NR_process_vm_readv syscall number. We use cmake to detect these situations and
fallback appropriately: in the first case, we can issue the syscall manually, while it the latter
case, we need to drop fast memory read support completely.
