[SPARK-18772][SQL] NaN/Infinite float parsing in JSON is inconsistent
## What changes were proposed in this pull request?
This relaxes the parsing of `Float` and `Double` columns to properly
support mixed case values of `NaN` and (+/-)`Infinity`, as well as properly
supporting (+/-)`Inf`. Currently a string literal of `Nan` or `InfinitY` will
cause a task to fail instead of placing the record in the corrupt record
column, and `Inf` causes a failure instead of being a valid double.
## How was this patch tested?
Additional unit tests have been added
