Rewrite debugger tuning test case to not depend on apple sections

Summary:
In a follow-up commit I'll 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
