[TRAFODION-2367] EXPLAIN documentation updates + syntax tweak
Three changes:
1. Noted in EXPLAIN documentation that some non-reserved keywords can be
used for statement names in PREPARE but cause syntax errors when used in
EXPLAIN. Noted that as a workaround, one can change the name to a delimited
identifier.
2. Tweaked the EXPLAIN syntax in the SQL parser to accept all one-letter
non-reserved keywords as statement names. So, for example, "explain c;" will
now work instead of raising a syntax error.
3. Fixed the EXPLAIN documentation to note that one can do "EXPLAIN
query_text" as well.
