Sigurd Schneider 4aa97de1af [conversions] Speed up double to CString conversion 
This addresses most of the regression in of
Kraken's json-stringify-tinderbox-orig with
31bit Smis: Many object properties become heap
numbers, and printing an integer which is
represented as a double is slower than printing
the integer directly.
