Jan Kratochvil 3f594ed168 Fix lookup of symbols at the same address with no size vs. size 
This fixes a failing testcase on Fedora 30 x86_64 (regression Fedora 29->30):

PASS:
./bin/lldb ./lldb-test-build.noindex/functionalities/unwind/noreturn/TestNoreturnUnwind.test_dwarf/a.out -o 'settings set symbols.enable-external-lookup false' -o r -o bt -o quit
  * frame #0: 0x00007ffff7aa6e75 libc.so.6`__GI_raise + 325

    frame #4: 0x0000000000401134 a.out`func_a at main.c:26:2

The extra ELF symbols are there due to Annobin (I did not investigate why this problem happened specifically since F-30 and not since F-28).
It is due to:

Symbol table '.dynsym' contains 2361 entries:
Valu e          Size Type   Bind   Vis     Name
0000000000022769   5 FUNC   LOCAL  DEFAULT _nl_load_domain.cold
