Summary: This re-applies {D5195} and {D5235}, they were reverted as part of diff stack to unbreak i386. The proper fix is done in {D5289}. Allocate bss section within proper range of other sections: * when `+RTS -xp` is passed, allocate it contiguously as we did for jump islands * when we mmap the code to lower 2Gb, we should allocate bss section there too Test Plan: 1. `./validate` 2. with ``` DYNAMIC_GHC_PROGRAMS = NO DYNAMIC_BY_DEFAULT = NO ``` `TEST="T15729" make test` passed in both linux (both i386 and x86_64) and macos. 3. Also test in a use case where we used to encouter error like: ``` ghc-iserv-prof: R_X86_64_PC32 relocation out of range: (noname) = b90282ba ``` and now, everything works fine.
