e3bda594ae Prefer __builtin_prefetch over inline asm
Reorder the ifdefs for the PREFETCH macros so that the compiler builtin is
favored over the inline assembly for aarch64.

0a8aacb4db Use stat() to Check that File Should be chmod()-ed
Rather than special-casing a check for `/dev/null`, this uses `stat()` to
avoid `chmod()`-ing any non-regular file. I believe this is the desirable
behavior. `UTIL_chmod()` is never called on directories at the moment, only
output files.

44fa052599 Introduce Variants of Various UTIL Functions that Take Pre-Populated stat_t Structs
Instead of calling `stat()`, these functions accept the result of a previous
`stat()` call on the file in question, which will allow us to make multiple
decisions around a file without redundant `stat()` calls.

b6e24bc4dc Rename UTIL_getFileStat() -> UTIL_statFile() and UTIL_getDirectoryStat() -> UTIL_statDir()
I want to introduce versions of many of these functions that take pre-
populated `stat_t` objects and use those rather than doing their own redundant
`stat()` internally. These functions will have `...Stat()` suffixes. So this
commit renames these existing functions into the active voice, to avoid
confusion.

new version easier to vectorize
leads to smaller code and faster execution
notably at the last recombination stage
(basically, fixed cost per block).
