DECOMPILER: Pure grouping option
...
The existing grouping algorithm doesn't work with non-stack-based
engines. Because dot is unable the large amount of vertices you get as a
result, this prevents visualization of the code flow. To get around
that, pure grouping provides an alternative which only considers
branches. This creates the minimal amount of vertices in the graph,
making it much easier for dot to layout the graph.

Rewrite function detection
...
The KYRA-specific function detection has been replaced with a generic,
opt-in function detection which converts unreachable code into
functions.
A post-processing step will be required to fill in metadata for code
generation; this has not yet been implemented.

Major overhaul of else detection
...
The else detection was horribly, horribly broken, leading to incorrect
and unbalanced output. This has now been revamped entirely, and all
SCUMMv6 scripts are at least balanced now. Additionally, various output
enhancements have been added.
Note: Short-circuit detection has been temporarily disabled, pending
proper handling. Consequently, one test, testShortCircuitDetection, is
currently *expected* to fail.
