Fix issue #62: emit stdlib code as char array, not a string

Browse Source 
MSVC 2010 issues an error if given a string larger than 64k characters
long.  To work around this, the pre-processed stdlib.ispc code is now
stored as an array of characters terminated with a NUL (i.e. the same thing
in the end); MSVC is fine with arrays larger than 64k characters.
