LOG: [RuntimeDyld] Guard UsedTLSStorage to x86 ELF only

UsedTLSStorage is only used in allocateTLSSection,
guarded in x87 ELF only.
So clang will emit error with -Werror on.

.../llvm/tools/llvm-rtdyld/llvm-rtdyld.cpp:288:12:
error: private field 'UsedTLSStorage' is not used
[-Werror,-Wunused-private-field]
  unsigned UsedTLSStorage = 0;
           ^

Added: 
    

Modified:

Removed:
