    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.

    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.
