Pass an ABI to choose_hard_reg_mode
choose_hard_reg_mode previously took a boolean saying whether the
mode needed to be call-preserved. This patch replaces it with an
optional ABI pointer instead, so that the function can use that
to test whether a value is call-saved.
default_dwarf_frame_reg_mode uses eh_edge_abi because that's the
ABI that matters for unwinding. Targets need to override the hook
if they want something different.
