Improve __atomic_clear/test_and_set documentation

Document that __atomic_clear and __atomic_test_and_set should
only be used with bool.

	* doc/extend.texi: Document that __atomic_clear and
	  __atomic_test_and_set should only be used with bool.

Fix HLE example in manual

The HLE example in the manual only commits when using bool
for the flag, because __atomic_clear only writes bool, and
HLE requires the acquire and release to match.

So when the example is copied with e.g. an int variable it
does not commit and causes slower than expected performance.

Some people are running into problems because of this.

Switch it over to use __atomic_store.

Also fix a minor typo nearby.

gcc/:
2013-06-21  Andi Kleen  <ak@linux.intel.com>

	* doc/extend.texi: Dont use __atomic_clear in HLE
	example.  Fix typo.
