LoongArch: Make the users of larch_insn_gen_break() constant
LoongArch defines UPROBE_SWBP_INSN as a function call and this breaks
arch_uprobe_trampoline() which uses it to initialize a static variable.
Add the new "__builtin_constant_p" helper, __emit_break(), and redefine
the current users of larch_insn_gen_break() to use it.
Fixes: ff474a78cef5 ("uprobe: Add uretprobe syscall to speed up return probe")
