This allows the test to work when srcdir != objdir.

32b30a3c23 Fix this test on Solaris. 
Solaris grep is more traditional and (AFAIK) does not support regexs.
Also, single quotes should disable all shell interpretation, so no
backslashes should be needed (and, in fact, keep Solaris from working).

50d435f3a7 Legalize for CTLZ generates a ctpop, but this ctpop is not expanded. 
This is bad.  It is generated if you are ctlz a type that is not
legal for the arch (aka ctlz of bytes on alpha legalize fine).
