middle-end: Remove integer_three_node [PR116537]
After the small expansion patch for __builtin_prefetch, the
only use of integer_three_node is inside tree-ssa-loop-prefetch.cc so let's
remove it as the loop prefetch pass is not enabled these days by default and
having a tree node around just for that pass is a little wasteful. Integer
constants are also shared these days so calling build_int_cst will use the
cached
node anyways.
Bootstrapped and tested on x86_64-linux.
PR middle-end/116537
gcc/ChangeLog:
* tree-core.h (enum tree_index): Remove TI_INTEGER_THREE
* tree-ssa-loop-prefetch.cc (issue_prefetch_ref): Call build_int_cst
instead of using integer_three_node.
* tree.cc (build_common_tree_nodes): Remove initialization
of integer_three_node.
* tree.h (integer_three_node): Delete.
