DO NOT MERGE Fix floating point to text conversion overflow
Any precision >=2147483647 will cause a buffer overflow.
For instance, executing the following statement will segfault
select (printf('%.2147483647G',0.01));
Later sqlite versions fixed this by hard-coding a hard-limit of
100k million on the precision of floating point to text conversions
https://sqlite.org/src/info/d08d3405878d394e
We fix this on earlier versions by setting the compile time flag
to the same 100k million
