    • Require equal shift amounts for IFN_DIV_POW2 · a0643f02 
      IFN_DIV_POW2 currently requires all elements to be shifted by the
same amount, in a similar way as for WIDEN_LSHIFT_EXPR.  This patch
enforces that when building the SLP tree.

If in future targets want to support IFN_DIV_POW2 without this
restriction, we'll probably need the kind of vector-vector/
vector-scalar split that we already have for normal shifts.

    • Check mask argument's type when vectorising conditional functions · 8a0ae3c1 
      We can't yet vectorise conditional internal functions whose boolean
condition is fed by a data access (or more generally, by a tree of logic
ops in which all the leaves are data accesses).  Although we should add
that eventually, we'd need further work to generate good-quality code.

Unlike vectorizable_load and vectorizalbe_store, vectorizable_call
wasn't checking whether the mask had a suitable type, leading to an
ICE on the testcases.

    • [AArch64] Use move-if-change for aarch64-tune.md · 03338111 
      If aarch64-tune.md was older than gentune.sh or aarch64-cores.def,
we'd try to overwrite it even if the current contents were correct.

    • libstdc++: Define __cpp_lib_three_way_comparison conditionally · f31a99f7 
      The contents of the <compare> header are not complete unless concepts
are supported, so the feature test macro should depend on the macro for
concepts.

As a result, the std::lexicographical_compare_three_way function will
not be defined unless concepts are supported, so there is no need to
check __cpp_lib_concepts before using concepts in those functions.
