  Don’t use additional linker flags to detect presence of -fno-pie in configure.ac
  
  This mirrors the behavior of ghc-toolchain

  Add HasCallStack to Control.Monad.Fail.fail
  
  CLC proposal https://github.com/haskell/core-libraries-committee/issues/327
  
  2% compile-time allocations increase in T3064, likely because `fail`
  is now marginally more expensive to compile.
  
  Metric Increase:
      T3064

  Bump containers submodule to 0.8
  
  Also
  
  * Disable -Wunused-imports for containers
  * Allow containers-0.8 for in-tree packages
  * Bump some submodules so that they allow containers-0.8. These are not
    at any particular versions.
  * Remove unused deps containers and split from ucd2haskell
  * Fix tests affected by the new containers and hpc-bin

  NCG/LA64: Optimize code generation and reduce build-directory size.
  
  1. makeFarBranches: Prioritize fewer instruction sequences.
  2. Prefer instructions with immediate numbers to reduce register moves,
    e.g. andi,ori,xori,addi.
  3. Ppr: Remove unnecessary judgments.
  4. genJump: Avoid "ld+jr" as much as possible.
  5. BCOND and BCOND1: Implement conditional jumps with two jump ranges,
    with limited choice of the shortest.
  6. Implement FSQRT, CLT, CTZ.
  7. Remove unnecessary code.
