0001 essentially reverts commit c6a43c2, and instead fixes the problem
(MSVC dislikes casts to the same type) by omitting the cast in the
problematic line in pg_lfind32(). While working on optimizing hex_encode()
and hex_decode() [0], I noticed that implicit conversions sufficed.
0002 optimizes vector8_has_le() on AArch64 by using vminvq_u8(). I needed
vector8_has_ge() for the hex_encode()/hex_decode() work and noticed this
opportunity.
