We may use the same macro for integer constants used in both
C and assembly codes. For 64bit integers in C, we use LL suffix.
But LL/L suffixes are rejected by assembler as in

[hjl@gnu-6 910]$ cat bad.s
.8byte 0x00000008007C0000ULL
.8byte 0x00000008007C0000UL
.8byte 0x00000008007C0000LL
.8byte 0x00000008007C0000L
.8byte 0x00000008007C0000ULl
.8byte 0x00000008007C0000Ul
.8byte 0x00000008007C0000Ll
.8byte 0x00000008007C0000l

I think we should allow C suffixes valid for for type valueT.
