[Bug target/111755] The built-in memset function in GCC inadvertently generates code like "vst1.8 {d8-d9}, [sp:64]", which assumes an 8-byte alignment on the stack pointer $sp, leading to alignment violations

--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The ARM EABI says the stack is always aligned to 8 byte so unless you change
GCC to be do this, this is exacted and the incoming stack needs to be aligned
correctly.
