commit r15-4488-gc886eb3421883a3ab70c6af79f271289cc8bb1d4

gcc/: Merge definitions of array_type_nelts_top
There were two identical definitions, and none of them are available
where they are needed for implementing a number-of-elements-of
operator. Merge them, and provide the single definition in
gcc/tree.{h,cc}, where it's available for that operator, which will be
added in a following commit.
gcc/ChangeLog:
* tree.h (array_type_nelts_top)
* tree.cc (array_type_nelts_top):
Define function (moved from gcc/cp/).
gcc/cp/ChangeLog:
* cp-tree.h (array_type_nelts_top)
* tree.cc (array_type_nelts_top):
Remove function (move to gcc/).
gcc/rust/ChangeLog:
* backend/rust-tree.h (array_type_nelts_top)
* backend/rust-tree.cc (array_type_nelts_top):
Remove function.
