4193	Add function to create new hashtables with a default size	japple	simonmar	"In other some standard libraries (Java, OCaml), hash tables can be created with a use-supplied size. This avoids rehashing for users who know they will be inserting a lot of data.

Data.HashTable does not expose a function to do this. This proposal changes that.

For a dictionary of 5 million strings, this patch saves me about 33% of the total execution time. For 10 million strings, this patch saves me 50% of the total execution time."	proposal	closed	high	7.0.1	libraries/base	6.12.2	fixed	hash, hash table		Unknown/Multiple	Unknown/Multiple	None/Unknown
