This patch adds an optimization into the NCG: for large strings
(threshold configurable via -fbinary-blob-threshold=NNN flag), instead
of printing `.asciz "..."` in the generated ASM source, we print
`.incbin "tmpXXX.dat"` and we dump the contents of the string into a
temporary "tmpXXX.dat" file.

See the note for more details.
