arm: Avoid indirection with -mpure-code on v6m (PR96967)
With -mpure-code on v6m (thumb-1), to avoid a useless indirection when
building the address of a symbol, we want to consider SYMBOL_REF as a
legitimate constant. This way, we build the address using a series of
upper/lower relocations instead of loading the address from memory.
This patch also fixes a missing "clob" conds attribute for
thumb1_movsi_insn, needed because that alternative clobbers the flags.
