This reverts commit 615eb855416ce536e02ed935ecc5a6f25519ae16. It was
originally intended to fix #24449, but it was merely sweeping the bug
under the rug. 3836a110577b5c9343915fd96c1b2c64217e0082 has properly
fixed the fragile test, and we no longer need the C version of genSym.
Furthermore, the C implementation causes trouble when compiling with
clang that targets i386 due to alignment warning and libatomic linking
issue, so it makes sense to revert it.

This commit fixes an unnoticed out-of-bound memory access of genSym on
32-bit. ghc_unique_inc is 32-bit sized/aligned on 32-bit platforms,
but we mistakenly treat it as a Word64 pointer in genSym, and
therefore will accidentally load 2 garbage higher bytes, or with a
small but non-zero chance, overwrite something else in the data
section depends on how the linker places the data segments. This
regression was introduced in !11802 and fixed here.

Without an understanding of immutable vs. mutable memory, the index
primop family have a potentially non-intuitive type signature:
indexOffAddr :: Addr# -> Int# -> a
readOffAddr :: Addr# -> Int# -> State# d -> (# State# d, a #)
indexOffAddr# might seem like a free generality improvement, which it
certainly is not!
This change adds a brief note on mutability expectations for most
index/read/write access primops.
