In function do_extractm() the mask is calculated as
dup_const(1 << (element_width - 1)). '1' being signed int
works fine for MO_8,16,32. For MO_64, on PPC64 host
this ends up becoming 0 on compilation. The vextractdm
uses MO_64, and it ends up having mask as 0.
Explicitly use 1ULL instead of signed int 1 like its
used everywhere else.
