[PR testsuite/114182] Fix minor testsuite issue when double == float

[Jeff Law]

This is a minor testsuite adjustment

attr-complex-method-2.c selects between two scan-tree-dump clauses based 
on avr, !avr.  But what they really should be checking is "large_double" 
that way it works for avr, h8, rl78 and any other target which makes 
doubles the same size as floats.

attr-complex-method.c should be doing the same thing.

After this change avr passes attr-complex-method.c and the rl78 and h8 
ports will pass both tests.  Other targets in my tester are unaffected.

Pushing to the trunk.
