Integration test for analysing the binary and extracting RzIL

[XVilka]

Is your feature request related to a problem? Please describe.

Currently we lack the example on how to extract RzIL from the binary, with all steps necessary to:

Describe the solution you'd like

Add a test/integration/test_analysis_rzil.c with these:

• Analyse the binary
• Extract RzIL for one instruction and for the whole function
• Evaluate a chunk of RzIL for a piece or a whole function

It's probably best to cover multiple architectures - e.g. x86, ARMv7, ARMv8, 8051 (for something more different than the mainstream)
