This turns EM `con 5000000000I8` into assembly `.data8 5000000000` for machines i386, i80, i86, m68020, powerpc, vc4. These are the only ncg machines in our build. i80 and i86 get con_mult(sz) for sz == 4 and sz == 8. The other machines only get sz == 8, because they have 4-byte words, and ncg only calls con_mult(sz) when sz is greater than the word size. The tab "\t" after .data4 or .data8 is like the tabs in the con_*() macros of mach/*/ncg/mach.h. i86 now uses .data4, like i80. Also, i86 and i386 now use the numeric string without converting it to an integer and back to a string.
