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`.

contain debug info (which in turn contain lots of mergeable strings.)

[AVX-512] Add support for changing VSHUFF64x2 to VSHUFF32x4 when its feeding a vselect with 32-bit element size.

Summary:
Shuffle lowering may have widened the element size of a i32 shuffle to i64 before selecting X86ISD::SHUF128. If this shuffle was used by a vselect this can prevent us from selecting masked operations.

This patch detects this and changes the element size to match the vselect.

I don't handle changing integer to floating point or vice versa as its not clear if its better to push such a bitcast to the inputs of the shuffle or to the user of the vselect. So I'm ignoring that case for now.

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).

[X86][SSE] Improve UINT_TO_FP v2i32 -> v2f64

Vectorize UINT_TO_FP v2i32 -> v2f64 instead of scalarization (albeit still on the SIMD unit).

The codegen matches that generated by legalization (and is in fact used by AVX for UINT_TO_FP v4i32 -> v4f64), but has to be done in the x86 backend to account for legalization via 4i32.
