[4.6/4.7] Fix some parser timers (issue4894054)

[4.6/4.7] Fix some parser timers (issue4894054)

[Diego Novillo]

Found while building our internal code base with -ftime-report.  This
patch is against google/gcc-4_6, but the bug also exists in 4.7 and
gcc-4_6-branch.

OK for gcc-4_6-branch and trunk?

Tested on x86_64.  Applied to google/gcc-4_6.


Diego.

	* name-lookup.c (lookup_arg_dependent): Use conditional
	timevars.
	* decl.c (xref_tag): Likewise.
	* call.c (build_op_call): Likewise.

For trunk.  The 4.6 branch looks very different.

Yes, I later realized that we had originally backported this timer patch 
from trunk to google's 4.6 branch.


Thanks.  Diego.
