This reverts commit c82770f57977a2b5add6e1378f234f8dd6153392.
The shellcheck suggestion is spurious and results in SUBST_TOOLDIR being a
no-op. `set` sets positional arguments for bash, but we want to set the variable
given as the first autoconf argument.
Fixes #24542
Metric decreases because the paths in the settings file are now shorter,
so we allocate less when we read the settings file.

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.

Type operators differ from term operators in that they are lexically
classified as (type) constructors, not as (type) variables.
Prior to this change, promoteOccName did not account for this
difference, causing a scoping issue that affected RequiredTypeArguments.
type (!@#) = Bool
f = idee (!@#) -- Not in scope: ‘!@#’ (BUG)
Now we have a special case in promoteOccName to account for this.
