3361 * gencode.c (MIPS_DECODE): Set UNSIGNED for multu instruction.

3364 extension for arithmetic shifts to not shift the number of bits in
3365 the type. Fix 64 bit multiply high word calculation. Fix 32 bit
3366 unsigned multiply. Fix ldxc1 and friends to use coprocessor 1.

3402 __int64 instead of `long long'. Change many refs to long long
3403 into word64/uword64 typedefs.
