[[PING][PATCH]] Use TREE_CODE to check for void return type in SIMD function clones for OpenMP.

This change fixes an issue where functions
decorated with:
pragma omp declare simd
that return void via a typedef would crash
GCC with an ICE while compiling a program
containing such a function, by comparing the
TREE_CODE of the type to VOID_TYPE instead of
directly comparing to void_type_node.

gcc/
	* omp-simd-clone.cc (simd_clone_adjust_return_type): Use TREE_CODE
and VOID_TYPE when checking for void return type in adjusted functions.
	(simd_clone_adjust): Likewise.

Hi all,

Just a ping for this patch of mine.
It fixes the ICE reported in the bugzilla item:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111856

The test openMP program no longer crashes GCC.

No merge conflicts with trunk as of 3rd August 2026.
Boostrapped and regression tested on
x86_64-pc-linux-gnu with enable-languages=all.
