Because in the MustBeInt opcode, the result of executing the
sql_check_types() function is not checked. The main functionality
of the function there is to convert mem if necessary and possible.

Removed two of them. However, in the next patch, I deleted the
entire test file after I transferred several tests to another
file.

Subject: [PATCH] sql: remove mem_apply_type() from OP_MustBeInt

This patch replaces mem_apply_type() with mem_check_types() in
OP_MustBeInt, which allows to remove implicit cast in some places,
for example, in the IN statement.

Part of #4230
