Log:
x32: Add addr32 prefix to VSIB address
32-bit indices in VSIB address are sign-extended to 64 bits. In x32,
when 32-bit indices are used as addresses, like in
vgatherdps %ymm7, 0(,%ymm9,1), %ymm6
32-bit indices, 0xf7fa3010, is sign-extended to 0xfffffffff7fa3010 which
is invalid address. Add addr32 prefix to UNSPEC_VSIBADDR instructions
for x32 if there is no base register nor symbol.
This fixes 175.vpr and 254.gap in SPEC CPU 2000 on x32 with
-Ofast -funroll-loops -march=haswell
