* [stdlib][SR-13883] Avoid advancing past representable bounds when striding.
* [stdlib] Expand a test and add a comment to ensure correct floating-point stride bounds checking.
* [stdlib][NFC] Clarify a comment in a test.
* [stdlib][NFC] Adjust copyright notices, clarify comments, delete '-swift-version=3' for tests.
* [stdlib] Add implementations for fixed-width integer strides for performance.
* [stdlib] Document `Strideable._step` and modify overflow checking behavior of `Stride*Iterator`.
* [stdlib] Address reviewer comments, postpone documentation changes
* [stdlib][NFC] Update documentation for '_step(after:from:by:)'
* [stdlib][NFC] Use 'nil' instead of an arbitrary value for integer striding '_step' index
This decreases total testing time by over a minute on my old Mac Pro.
It probably has much less effect on systems with fewer cores, but shouldn't
be any worse there.

This takes all %target-run-simple-swift and %target-run-stdlib-swift
invocations and runs them using the interpreter instead. To enable this
mode, pass --param=interpret to lit.py; you can add this flag to the
LLVM_LIT_ARGS CMake setting (which defaults to "-sv").
This doesn't support separated %target-build / %target-run steps, nor
does it work with StdlibUnittest (which uses posix_spawn to run its
subtasks). But it's a start.

The test harness now can recover after test crashes, allowing:
- check for crashes themselves (without reporting them to the Python lit driver,
which is about 10x slower -- even if CrashTracer is disabled);
- recover from unexpected test crashes and run the rest of the tests;
- this lays the groundwork for assertions that end the test execution, but
allow the rest of the tests to run (rdar://17906801).
Note that we don't spawn a fresh process for every test. We create a child
process and reuse it until it crashes.

Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able." Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.
There are obvious improvements to make in some of these names, which can
be handled with separate commits.
Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.
