The actual binaries for atomic-load-int128.c  at -O1 and higher run fine on
x86_64-apple-darwin64 at -m64. However they take around 16 seconds to execute
on a...

      Model Name: Mac Pro
      Model Identifier: MacPro3,1
      Processor Name: Quad-Core Intel Xeon
      Processor Speed: 2.8 GHz
      Number of Processors: 2
      Total Number of Cores: 8
      L2 Cache (per Processor): 12 MB
      Memory: 12 GB
      Bus Speed: 1.6 GHz

Increasing the timeout to 20 seconds allows all of the
gcc.dg/simulate-thread/atomic-load-int128.c tests to pass.
