Widen valu_t in the assembler to 64 bits.

Browse source 
Most machines had undefined valu_t and redefined it to a different
type.  Edit mach/*/as/mach0.c to remove such redefinitions, so the
next change to valu_t will affect all machines.

Edit mach/proto/as/comm0.h to change valu_t to int64_t, and add
uvalu_t and uint64_t.

Remove int64_t y_valu8 from the yacc %union, now that valu_t y_valu
can hold 64 bits.  Replace y_valu8 with y_valu.  The .data8 pseudo
becomes less special; it now accepts absolute expressions.

This change simplifies the assembler and seems to have no effect on
the assembled output.  Among the files in share/ack/examples, the only
changes are in hilo_bas.* and startrek_c.linuxppc, but those files
seem to change whenever I rebuild them.

.fi
The range of numbers depends on the machine.
A rule of the thumb is that the width of the machine's registers
the same is as the number of bits allowed in numbers.
The width of numbers is at least 64 bits, so the .data8 pseudo may
accept the full range of 8-byte values.
