Add framework for switching certs based on signature_algorithms TLS extension.
Summary: Added support for switching SSLContexts based on the signature_algorithms
extension.
This diff does not currently include any logic for determining which certs use
SHA1 or not.
Some thoughts:
- This is a little scary since it defaults to SHA1 (assuming the client can't support
SHA256 if we don't see SHA256 specifically in the hello extension). We need to
be 100% sure that all clients that are going to reject SHA1 are sending this,
and that we identify it correctly.
- We should add logging to see when we think a client needs SHA1, when we
actually give SHA1, etc. I'm not sure what the best way to do this is with our
logging infrastructure.
- This is not setup to serve any SHA1 certs to SHA256 supporting clients.

Summary: Right now ThreadLocal & friends don't operate correctly when used as a

allocated in the static constructor so anybody who uses the ID prior to
first use would use an invalid ID. This makes ThreadLocal unusable for core
code such as per-thread reference counting.
This diff allocates the ID on first use. By making the invalid ID maxint we
avoid adding any extra branches in the fast path. We can then make the
constructor a constexpr meaning that initialization will happen prior to
any code running.

Support SSE-enabled Range functions under Clang
Summary: [Folly] Support SSE-enabled `Range` functions under Clang.
Basically, we remove GCC-only -isms. In particular, we use only names from the `<emmintrins.h>` and `<smmintrins.h>` headers, instead of the GCC-specific SSE builtins that the original code uses.
But in order to get this to work, we must split out the SSE-enabled functions into their own sources and compile them with the `-msse4.2` flag. There is a way to get around this in GCC by marking individual functions as SEE-enabled, but that technique is not supported in Clang. This is the new `RangeSse42` module.
And in order to do that, we must split out the code that is called by both the original `Range` and the new SSE-enabled functions into yet a third module, `RangeCommon`.
Ahhhhhh, dependencies.
Note that we always compile the SSE-enabled functions, but we only run them on architectures supporting SSE. The original code tests the CPU's capabilities before running any SSE-enabled functions; this change retains that check.
