[PATCH] PPC NCG: Generate clear right insn at arch width
The clear right immediate (clrrxi) is only available in word and
doubleword width. Generate clrrxi instructions at architecture
width for all MachOp widths.

ghc-prim: Use C11 atomics
Previously `ghc-prim`'s atomic wrappers used the legacy `__sync_*`
family of C builtins. Here we refactor these to rather use the
appropriate C11 atomic equivalents, allowing us to be more explicit
about the expected ordering semantics.

hadrian: Pass -DNOSMP to C compiler when needed
Hadrian passes the -DNOSMP flag to GHC when the target doesn't support
SMP, but doesn't pass it to CC as well, leading to the following

The old make system correctly passed this flag to both GHC and CC [1].
Fix this error by passing -DNOSMP to CC as well.

CmmToC: fix CmmRegOff for 64-bit register on a 32-bit target
We used to print the offset value to a platform word sized integer.
This is incorrect when the offset is negative (e.g. output of cmm
constant folding) and the register is 64-bit but on a 32-bit target,
and may lead to incorrect runtime result (e.g. #22607).
The fix is simple: just treat it as a proper MO_Add, with the correct
width info inferred from the register itself.
Metric Increase:

Bump supported LLVM range from 10 through 15 to 11 through 16
LLVM 15 turns on the new pass manager by default, which we have yet to
migrate to so for new we pass the `-enable-new-pm-0` flag in our
llvm-passes flag.
LLVM 11 was the first version to support the `-enable-new-pm` flag so we
bump the lowest supported version to 11.
Our CI jobs are using LLVM 12 so they should continue to work despite
this bump to the lower bound.

Use native x86_64 instructions on x32
This patch enables a few native 64-bit integer instructions
on x32 which are available on this architecture despite using
32-bit pointers. These instructions are present on x86_64 but
not on x86 and ghc checks the size of (void *) to determine
that. This method fails on x32 since despite using 32-bit
pointers and hence sizeof(void *) == 4, it still uses the
full x86_64 instruction set and software-emulated variants
of the aforementioned 64-bit integer instructions are
therefore not present in the toolchain which will make ghc
fail to build on x32.
