This commit introduces support for native library calls on the
i386 target. When encountering special instructions reserved
for native calls, this commit extracts the function name and
generates the corresponding native call.

This commit implements a shared library, where native functions are
rewritten as special instructions. At runtime, user programs load
the shared library, and special instructions are executed when
native functions are called.

Introduce a new test for native calls to ensure their functionality.
The process involves cross-compiling the test cases, building them
as dynamically linked binaries, and running these binaries which
necessitates the addition of the appropriate interpreter prefix.
