x86: Don't use the strict copy checks when branch profiling is in use

The branch profiling creates very complex code for each if
statement, to the point that gcc has trouble even analyzing
something as simple as

  if (count > 5)
      count = 5;

This then means that causing an error on code that gcc cannot
analyze for copy_from_user() and co is not very productive.

This patch excludes the strict copy checks in the case of branch
profiling being enabled.
