Stephen Long c9dc750058 tcg: Fix tcg gen for vectorized absolute value 
The fallback inline expansion for vectorized absolute value,
when the host doesn't support such an insn was flawed.

E.g. when a vector of bytes has all elements negative, mask
will be 0xffff_ffff_ffff_ffff. Subtracting mask only adds 1
to the low element instead of all elements becase -mask is 1
and not 0x0101_0101_0101_0101.
