ArrayList uses `items` slice to store len initialized items, while
PriorityQueue stores `capacity` potentially uninitialized items.
This is a surprising difference in the API that leads to bugs!

The wrong `size_class` was used when fetching stack traces from empty
buckets. The `size_class` would always be the maximum value after
exhausting the search of active buckets rather than the actual
`size_class` of the allocation.
Empty buckets have their `alloc_cursor` set to `slot_count` to allow the
size class to be calculated later. This happens deep within the free
function.
This adds a helper and a test to verify that the size class of empty
buckets is indeed recoverable.
Not really useful after old C++ compiler removal, and
zig build has own cache system. If someone still wants it,
`CMAKE_C_COMPILER_LAUNCHER` and `CMAKE_CXX_COMPILER_LAUNCHER` exist.
From CMake docs:
> RULE_LAUNCH_COMPILE
> Note: This property is intended for internal use by ctest(1).
> Projects and developers should use the <LANG>_COMPILER_LAUNCHER
> target properties or the associated CMAKE_<LANG>_COMPILER_LAUNCHER
> variables instead.

Set `ZIG_PIE` default to be same as `CMAKE_POSITION_INDEPENDENT_CODE`, and
add check for situation when `ZIG_PIE` is set to True but CMake does not
support compiling position independent code. CMake's support is needed
for "zigcpp" target.
Also remove temporary variables for constructing `ZIG_BUILD_ARGS`,
instead use `list(APPEND ...)` functions.
Also remove long unused `ZIG_NO_LANGREF` variable.

Replace `CMAKE_SOURCE_DIR` and `CMAKE_BUILD_DIR` with different variables,
or in some cases just remove them.
For some function arguments, prepended `CMAKE_SOURCE_DIR` was removed without
replacement. This includes:
* Sources for `add_library` and `add_executable` (`ZIG_CPP_SOURCES` and `ZIG_WASM2C_SOURCES`)
* Inputs for `configure_file` and `target_include_directory`
* For arguments above, CMake already prepends
`CMAKE_CURRENT_SOURCE_DIR` to them by default, if they are relative paths.
Additionaly, it was removed from arguments of commands that have `WORKING_DIRECTORY` set to
`PROJECT_SOURCE_DIR`, they will be similarly converted by CMake for us.
Also:
* Move project declaration to the top so that these variables are
available earlier.
* Avoid calling "git" executable if ".git" directory does not exist.
* Swap "--prefix" and `ZIG_BUILD_ARGS` arguments in cmake/install.cmake
to match same "zig2 build" command in CMakeLists.txt and allow
overriding "--prefix" argument

They were introduced in https://github.com/ziglang/zig/pull/3467 and
5b51f41ceed6604b388b63d73360a22d1ea95749 , and become obsolete since
C++-based compiler was removed: all C or C++ sources built by CMake
are just intermediate steps in bootstrapping.

* Localize most of the global properties and functions, for some time
they are only needed for "zigcpp" static library (sometimes with PUBLIC
keyword, so that it will propagate to zig2): `CMAKE_*_OUTPUT_DIRECTORY`
and two calls to `include_directories`. This removes useless flags when
building other targets and cleans build log a bit.
* Remove `EXE_CXX_FLAGS` variable, instead use more appropriate specific
properties and functions for this target. This gives better errors if
compiler does not support some of them, and CMake also handles for us
duplicate flags. It's also easier to read side-by-side with same
flags from build.zig .
* Add some comments.

* Revert "Revert "Merge pull request #19349 from nolanderc/save-commit""
This reverts commit 6ca4ed5948d8eaab28fc5e3706aeb1b113a210af.
* update to new URI changes, rework `--save` type
* initialize `latest_commit` to null everywhere
this one is even harder to document then the last large overhaul.
TLDR;
- split apart Emit.zig into an Emit.zig and a Lower.zig
- created seperate files for the encoding, and now adding a new instruction
is as simple as just adding it to a couple of switch statements and providing the encoding.
- relocs are handled in a more sane maner, and we have a clear defining boundary between
lea_symbol and load_symbol now.
- a lot of different abstractions for things like the stack, memory, registers, and others.
- we're using x86_64's FrameIndex now, which simplifies a lot of the tougher design process.
- a lot more that I don't have the energy to document. at this point, just read the commit itself :p
