Remove binaries in `src/Simulation/Native/` (`*_test` files)

2

In the path https://github.com/microsoft/qsharp-runtime/tree/main/src/Simulation/Native there's a number of binary files whose name ends with `_test`. Those are test executables (in ELF format, likely for Linux) generated during the build. We...

Develop a consistent strategy on "automatically resetting or not resetting all qubits on release".

[Discussion](https://github.com/microsoft/qsharp-runtime/pull/918#discussion_r792769094). **Copy:** cgranade This appears to automatically reset all qubits on release, but that's not the semantics used in any other of our simulators, I believe. I know @swernli led...

Sparse Simulator Sec: Cassandra: Apologies that this is somewhat tangential, but I note from this description [Sparse Simulator Sec] that the new simulator [Sparse Simulator] is not considered experimental like...

After [this PR](https://github.com/microsoft/qsharp-runtime/pull/889) is merged (the Native Simulator (NS) is migrated to Clang), the NS will be built with Ninja generator on Windows, but without Ninja on Mac and Linux...

The [actual implementation](https://github.com/microsoft/qsharp-runtime/blob/7736de760cf2ae9b3a099ba8df9713fffe453005/src/Qir/Runtime/lib/QIR/callables.cpp#L161-L169) of `__quantum__rt__capture_update_reference_count` `__quantum__rt__capture_update_alias_count` violates the [spec](https://github.com/qir-alliance/qir-spec/blob/main/specification/v0.1/2_Callables.md), see the end of the page: "Does nothing if the memory management table pointer or the function pointer at that index...

After migrating the [native simulator](https://github.com/microsoft/qsharp-runtime/tree/main/src/Simulation/Native) from GCC to Clang there is a number of warnings. See [tmp PR](https://github.com/microsoft/qsharp-runtime/pull/881), [GitHub issue](https://github.com/microsoft/qsharp-runtime/issues/876). Resolve those (Debug and Release). Make another pass through the...

src\Simulation\Native\src\simulator\kernels.hpp ```c++ template unsigned getvalue( std::vector const& wfn, unsigned q, double eps = 100. * std::numeric_limits::epsilon()) ``` With GCC no problems. With clang returns something unexpected in _release_ config on...

src\Simulation\Native\build-native-simulator.ps1 The option `-fsanitize=unsigned-integer-overflow` reports overflows in NativeSimulator. Strictly speaking unsigned integer overflow is _not_ an undefined behavior, but is not always intended. The option should be disabled for specific...

Consider ceasing using Ninja on Mac and Linux

Currently QIR RT has CMake use Ninja build agent. I believe that Ninja is only required on Windows (without it CMake always uses MSVC compiler instead of clang), and is...
