Bug#38296 (low memory crash with many conditions in a query)
The parser code in sql/sql_yacc.yy needs to be more robust to out of
memory conditions, so that when parsing a query fails due to OOM,
the thread gracefully returns an error.
Before this fix, a new/alloc returning NULL could:
- cause a crash, if dereferencing the NULL pointer,
- produce a corrupted parsed tree, containing NULL nodes,
- alter the semantic of a query, by silently dropping token values or nodes
With this fix:
- calls to new/alloc are tested for a NULL result,
- OOM conditions cause the parser to stop immediately (MYSQL_YYABORT)
