Chennes 74d4f0ed66 [BugFix] Fix make_int sign-extending negative int8 lanes (#2438) ...

T.fill of an int8 buffer with a negative scalar (other than -1) silently
wrote only 1 of every 4 elements correctly and clobbered the other 3 to
-1. The vectorized fill packs four int8 lanes into one 32-bit store via
make_int(v,v,v,v); a negative signed char is integer-promoted to int and
sign-extended before the shifts/OR, so its high 1-bits flood the
neighbouring lanes (e.g. make_int(-7,-7,-7,-7) returned 0xFFFFFFF9 =
[-7,-1,-1,-1]).

Build the packed value from explicit unsigned bytes so the sign-extension
bits cannot leak across lanes. Add an int8 negative-fill regression test.

Fixes #2427
