Teach some ncg machines to use .data8

Browse source 
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.
