      Add a special case for erase(begin(), end()) to reset the control bytes. The motivation is to avoid potentially expanding the table unnecessarily later.

Note: I prefer doing this as a special case in erase(iterator, iterator) rather than special casing erase(iterator) for size==1 because IIUC that changes the time complexity of erase(iterator) from O(1) to O(N) and in pathological cases, it could change loops from O(N) to O(N^2).

    • Rename `absl::NonNull` to `absl::Nonnull`. · 93ef827f 
      The current spelling is inconsistent with standard casing rules: "nonnull" is a single word, not two.

    • symbolize_test: Add an indirection for getting the PC from function ptr. · c26cd952 
      Don't assume that function ptr == PC. Adds a redirection mechanism, GetPCFromFnPtr, and enables more test cases for Emscripten/Wasm.

On many (most?) platforms, the address of a function ptr is the same as its
Program Counter (PC) for the purpose of most things, including symbolization.

In Emscripten WebAssembly, the function ptr is just an index into a table of
functions. However, the name section maps function names to their literal
offsets into a Wasm binary. The WasmOffsetConverter is actually capable of both
indirections, so we can effectively go from function ptr to offset into the
binary (which is typically the "PC" for other Stack dumping things in Wasm,
including `emscripten_pc_get_function`).

More info: https://www.w3.org/TR/wasm-js-api-2/#exported-function-exotic-objects

Also fix Emscripten symbolize handling for `nullptr` now that we have tests for
that.

    • Correct std::optional/variant/any auto-detection for Apple platforms. · 512af68a 
      In Xcode 14.3, Apple modified the OS versions which support these
three types to exclude iOS 11 and watchOS 4. Update abseil accordingly.

Those versions of the OS did _not_ actually support the types, and any
binaries which used these types, built with prior Xcode versions,
would've crashed on startup on an actual iOS 11 or watchOS 4 device
due to missing symbols. As of Xcode 14.3, using them is now, correctly,
a build failure.

This change also drops the conditionals for pre-Xcode 12.5, as that is
no longer a supported version.
