Support floating point NaN and (-)Infinity values in remaining dialects

Continuing with #11704, here are some remaining dialects whose NaN or Infinity floating point values are not yet supported:

[ ] Access: Search for INF or NAN in the string version of the value: https://stackoverflow.com/q/33192022/521799
[ ] Sybase ASE: NaN or Inf: http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.infocenter.dc36271.1550/html/blocks/blocks27.htm
[ ] Sybase SQL Anywhere: NaN or Inf: http://infocenter.sybase.com/help/topic/com.sybase.dbrfen10/pdf/dbrfen10.pdf
[ ] Teradata: NaN or Inf (only unauthoritative docs found, to be verified)

These dialects would require formal support for vendor specific float types, first:

[x] Db2: SNAN or INFINITY https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.sql.ref.doc/doc/r0000731.html (only for DECFLOAT)
- Though, CAST('NaN' AS DECFLOAT) and CAST('Infinity' AS DECFLOAT) also seems to work, so let's leave it at that.
[ ] Informix: Nan, Infinity, -Infinity: https://www.ibm.com/support/knowledgecenter/SSGU8G_11.70.0/com.ibm.jccids.doc/src/tpc/imjcc_cjv00003.htm (only for DECFLOAT)
[ ] Oracle: 0f/0, 1f/0, -1f/0 (only for BINARY_DOUBLE and BINARY_FLOAT)
