Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
...
Moved the key statistics update to info().
The table is not locked in open(). This made wrong stats possible.
No test case for the test suite.
This happens only with heavy concurrency.
A test script is added to the bug report.

BUG#8924 'Explain' shows different strategy
...
- If number of records in table is 4, the calculated cost for using "index" and "range" become so close so that any rounding errors becomes visible.
- Added one more record to the tables for heap test and expoect "range" to be selected
- Decrease number of records in t1 for range and expect "index" to be choosen.
