[runtime] Expose reportToDebugger as swift_reportToDebugger.
...
...so that the overlays can use it. See next commit.

Remove the hash function from the runtime's exclusive access checks.
...
I expect this to improve the following Onone benchmarks:
- 1.09x accessGlobal
- 1.08x accessInMatSet
- 1.06x accessIndependent
And the preexisting benchmarks:
| TEST | DELTA | SPEEDUP |
| | | |
| Random | -7.9% | **1.09x** |
| MatMul | -7.6% | **1.08x** |
| XorShift | -7.2% | **1.08x** |
| PolymorphicCalls | -6.2% | **1.07x** |
| NopDeinit | -6.1% | **1.06x** |
| Ary | -6.0% | **1.06x** |
| Integrate | -5.8% | **1.06x** |
| StringWalk | -5.5% | **1.06x** |
| ArrayInClass | -5.2% | **1.06x** |
| MultiFileTogether | -5.2% | **1.06x** |
| DictionaryHashableClass | -5.2% | **1.05x** |
| MultiFileSeparate | -4.9% | **1.05x** |

Improve reporting of @objc inference issues from the Swift runtime ( #10406 )
...
* Extend Swift runtime issue reporting for @objc inference to include details about the declaration of the method (that is missing the @objc annotation) and a suggested fix-it. This changes the ABI of RuntimeErrorDetails, so we're also bumping the version.
* Update SwiftObject.mm

Change the signature of reportToDebugger and _swift_runtime_on_report to avoid using 'bool'. It's much easier to work with native-width integers only in LLDB. ( #10523 )

Fix some embarrassing list-management bugs with the exclusivity runtime
...
which can arise when accesses are not strictly nested.

Debugger hook/breakpoint for issue reporting from the Swift runtime ( #10293 )
...
* Implements a debugger hook (breakpoint) API and data structure. This structure is passed to the debugger and describes extra information about a fatal error or a non-fatal warning, which should be logged as a runtime issue.
This debugger hook is then used from two places, which currently only log to stderr:
- Runtime exclusivity violations.
- Swift 3 implicit Obj-C entrypoints.
A subsequent LLDB support will be able to catch these callbacks and show the runtime issues in a better way than just logging them to stderr. When the debugger is not attached, this shouldn't have any effect.

Make the exclusivity-set tracking a singly-linked list.

We'll use this space for something else in a follow-up.
