  [X86] Explicitly initialize __cpu_features2 global in compiler-rt to 0.

Seems like this may be needed in order for the linker to find the
symbol. At least on my Mac.

  Log Message:
  -----------
  [X86] Combine to two feature variables in __cpu_indicator_init into an array and pass them around as pointer we can treat as an array.

This simplifies the indexing code to set and test bits.

  Log Message:
  -----------
  [X86] Combine the three feature variables in getHostCPUName into an array and pass it around as an array reference.

This makes the setting and clearing of bits simpler.
