lib/runtime: mars.mars_string_to_c_string now correctly extracts integers from GMP format.

1241. By Matt Giuca on 2011-05-14

lib/runtime: Rewrite a lot of builtins to use the GMP library rather than casting ints to pointers (such builtins now work with bigints).
Note that this is highly unstable; any builtins which haven't been changed will treat pointers as integers.
This build is utterly broken.

lib/runtime: Change the type of Int to a mpz_ptr (mpz_t*).
Ints are now conceptually represented as pointers to GMP big integers. However, currently the implementation still just casts 32-bit ints to pointers as it always has (so it doesn't actually work for big ints).

backend_llvm: ld_intlit now compiles to a call to mars.new_int_si, rather than directly casting to an i8*.
This will be compatible with a future change of the definition of the %Int type.

lib/runtime: Added declarations of a bunch of libgmp functions.

1237. By Matt Giuca on 2011-05-14

lib/runtime: Added @mars.new_int_0 and @mars.new_int_si.

1236. By Matt Giuca on 2011-05-14

Makefile: Mars is now linked with libgmp, which will be required by the runtime system.

1235. By Matt Giuca on 2011-05-14

backend_llvm: Correctly bitcast the result of ld_field if required.

1234. By Matt Giuca on 2011-05-14

lib/runtime: Fix __impure_is type (return %Int instead of %Any).

1233. By Matt Giuca on 2011-05-14

lib/runtime: div and mod now perform adjustments to use floored division rather than truncated division.
Two test_builtin cases now pass.
