[X86] Add a hasOneUse check to selectScalarSSELoad to keep the same load from being folded multiple times.
Summary: When selectScalarSSELoad is looking for a scalar_to_vector of a scalar load, it makes sure the load is only used by the scalar_to_vector. But it doesn't make sure the scalar_to_vector is only used once. This can cause the same load to be folded multiple times. This can be bad for performance. This also causes the chain output to be duplicated, but not connected to anything so chain dependencies will not be satisfied.

Parallelize uncompress() and splitIntoPieces().
Uncompressing section contents and spliting mergeable section contents
into smaller chunks are heavy tasks. They scan entire section contents
and do CPU-intensive tasks such as uncompressing zlib-compressed data
or computing a hash value for each section piece.
Luckily, these tasks are independent to each other, so we can do that
in parallel_for_each. The number of input sections is large (as opposed
to the number of output sections), so there's a large parallelism here.
Actually the current design to call uncompress() and splitIntoPieces()
in batch was chosen with doing this in mind. Basically what we need to
do here is to replace `for` with `parallel_for_each`.
It seems this patch improves latency significantly if linked programs
contain debug info (which in turn contain lots of mergeable strings.)

Merge Linux and FreeBSD arm64 register contexts
Summary:
This is a test-the-water change about possibilities of reducing duplication in
the register context definitions.
I've named the new class RegisterInfoPOSIX, as RegisterContextPOSIX was already
taken :(. The two files were identical except for a fix by Tamas in D12636,
which was applied to the Linux version only, which fixed a discrepancy between
the definitions of fpsr and fpcr on one hand, and all other floating point
register definitions on the other.
Linux test suite still passes after this change. For freebsd, make the floating
point register behavior consistent, but I don't know whether it will be
consistently fixed, or consistently broken. By eyeballing the code, I have a
feeling that a similar fix to D12636 will be required in
RegisterContextPOSIXProcessMonitor_arm64::ReadRegister, but I can't be sure as I
have no way to test it (the assert in that function should fire upon accessing
the registers if it is wrong though).

[ELF] - Add support for access to most of synthetic sections from linkerscript.
This is important for cases like:
.sdata : {
*(.got.plt .got)

}
That was not supported before as there was no way to get access to
synthetic sections from script.

[XRay][compiler-rt] XRay Buffer Queue
Summary:
This implements a simple buffer queue to manage a pre-allocated queue of
fixed-sized buffers to hold XRay records. We need this to support
Flight Data Recorder (FDR) mode. We also implement this as a sub-library
first to allow for development before actually using it in an
implementation.
Some important properties of the buffer queue:
- Thread-safe enqueueing/dequeueing of fixed-size buffers.
- Pre-allocation of buffers at construction.

[tsan] Add support for GCD dispatch_suspend and dispatch_resume
GCD queues can be suspended and resumed with dispatch_suspend and dispatch_resume. We need to add synchronization between the call to dispatch_resume and any subsequent executions of blocks in the queue that was resumed. We already have an Acquire(q) before the block executes, so this patch just adds the Release(q) in an interceptor of dispatch_resume.
