538d624770 core: apply Real affinity on columns stored as int
Values in sqlite3, as expected, can be stored in different formats to
optimize disk usage. In this case, a 79.0 float will be transformed to a
u8.

sqlite3 deals with this by adding a RealAffinity op after each column
that might need it. Therefore, in this pr we do exactly that :).

30ec86a81e Add sorter utility functions and opcodes
This adds basic in-memory sorting utility functions, similar to SQLite's
src/vdbesort.c. We need to improve this later with external sorting so
to support large data sets.

This also adds sorting functionality to the VDBE. Note that none of this
is wired to SQL translation yet so it's unused for now.

2f3c3b5404 Clean up insn_to_str()
The SQLite documentation explicitly says that P1, P2, and P3 are 32-bit
signed integers. P4 is a value, and P5 is a 16-bit unsigned integer.
Although we use different types for operands, the `EXPLAIN` output
should be compatible with SQLite and, therefore, use those types.
