Tested on x86_64-pc-linux.

This patchset provides the final changes for PR108030 and resolves 
PR108856. The latter is a pure optimization and could wait for Stage 1 (I'm 
submitting the patch because simd is experimental/TS)

Matthias Kretz (8):
  libstdc++: Simplify three helper functions into one
  libstdc++: Fix simd build failure on clang
  libstdc++: More efficient masked inc-/decrement implementation
  libstdc++: Add missing constexpr on simd shift implementation
  libstdc++: Always-inline most of non-cmath fixed_size implementation
  libstdc++: Fix formatting
  libstdc++: Fix -Wsign-compare issue
  libstdc++: Test that integral simd reductions are precise
