Summary:
The type-erased Function is widely used with lambdas and the type of every lambda is unique. Template instantiations are costly for build speed so, for the parts of Function which interact with lambdas, we choose techniques to optimize build speed.

In particular, we avoid the extra layer of constructor templates which must be overload-tested and instantiated. The existing design of the extra layer was clean - it effectively used tag-dispatch and was able to deduplicate code with the coercing constructor. However, the choice of techniques was not optimal for build speed.

Summary:
When trying to bring react-native-macos up to date with 0.66, I was running into an issue getting RNTester to compile due to an error regarding redefining `clockid_t`. Other people have been seeing similar issues as per [these search results](https://github.com/facebook/folly/issues?q=clockid_t).

The history behind this appears to be as follows:

Several declarations in `<time.h>` were not available on Apple platforms until macOS 10.12 and iOS 10, which is why Folly needs to check the minimum version and set `FOLLY_HAVE_CLOCK_GETTIME` as needed. The problem is, the current logic as it stands right now is to set `FOLLY_HAVE_CLOCK_GETTIME = 1` (which implies that we don't need to declare them ourselves as the OS provides them for us) if...
* ...we're building for macOS, and the minimum required version is less than 10.12, or...
* ...we're building for iOS, and the minimum required version is less than 10.

However, this doesn't make any sense. This is saying that we don't need to declare these missing APIs if we could be compiling Folly for use on an older version (i.e., macOS 10.11/iOS 9 or earlier), which is totally wrong! Instead, we ought to be checking if the versions are *at least* macOS 10.12 or iOS 10.

React Native currently works around this by eliminating the minimum version check entirely with [this PR](https://github.com/facebook/react-native/pull/32715/), which is certainly a valid local fix ([the minimum iOS version for React Native apps is currently iOS 11](https://github.com/facebook/react-native/blob/1b31d6bb582768ccbe92d3c1a9e43354a8c531e5/template/ios/Podfile#L4)), but doesn't solve the problem at its core. This PR does solve the problem.

I have not tested building this with a minimum version below the above thresholds for use on a modern version of macOS/iOS, but considering the discussion in https://github.com/facebook/folly/issues/1545, I think we should be safe to ignore these older versions from now on.

Notes:
* For some versions of gcc, the compiler sees the converting-move-ctor as a better match than the actual move-ctor and this leads the compiler to infinite recursion; to work around this, explicitly exclude the same-type case of the converting-move-ctor.
* `std::exchange` on `exec_` would be incorrect for self-move because of order of operations.
* `std::exchange` on `call_` might be correct but it would be an extra template instantiation which is not desireable for `folly::Function`.

Summary:
A long time ago, getdeps scheduled each build up to the number of hardware threads. For some builds, that was too heavy, so it got throttled back to only ever use half the hardware threads. This left parallelism on the table for CPU-bound projects that don't use much RAM per compilation.

This commit makes better use of the hardware with finer-grained logic that allows each manifest to specify a `job_weight_mib` estimate in MiB, and limit concurrency to `available_ram / job_weight`.

Summary:
The flip operation, like the set and reset operations, are optimizable on x86-related architectures using the `btc` instruction, compared with `bts` and `btr` for set and reset operations.

The optimization is done for gnu-like compilers. However, for MSVC, there is no interlocked intrinsic for `btc`, so the optimization is not done.

Summary:
Function implements move and nuke operations via a type-erased pointer to an exec function. Both operations are explicitly noexcept but the function pointer which these operations call is not marked as noexcept. So the compiler emits unnecessary exception-handling code/data around the call. The exception-handling stuff make generated code larger and in theory may also hinder possible optimizations.

But when the exec function pointer as marked as `noexcept`, the compiler may elide the exception-handling stuff, shrinking generated code and in theory permitting a class of optimizations.

It is not possible for the underlying move operation to throw an exception since, if the move operation of the contained callable could throw an exception, the contained callable would be on-heap and not in-situ, and the underlying move operation would just be an infallible relocation of the in-situ `Function` state.

It is possible for the underlying nuke operation to throw an exception since the destructor of the contained callable could throw an exception. But this is rare. In this case, the exec function would contain exception-handling stuff; but in general, it would not. And this would merely moves where the exception-handling stuff is for the nuke operation, from one side of the type-erasure to the other side.
