In a follow-up commit I'd like to change the rules for emission of
accelerator tables, which means we won't be able to use them as a litmus
test for the debugger tuning options. Instead of sections, I base the
test on the presence/absence of some debug info attributes and opcodes:
LLDB - prefers DW_OP_form_tls_address and uses DW_AT_APPLE_optimized
GDB - prefers DW_OP_GNU_push_tls_address and does not use the optimized
attribute
SCE - prefers DW_OP_form_tls_address and does not use the optimized
attribute
