This patch is to add _Complex type in vararg testing.

Run varargs.exp on i686-pc-linux-gnu, get new two KFAIL. Note that PR
12776 is opened to track this problem.

KFAIL: gdb.base/varargs.exp: print find_max_double_real(4, dc1, dc2,
dc3, dc4) (PRMS: gdb/12776)
KFAIL: gdb.base/varargs.exp: print find_max_double_real(4, dc1, dc2,
dc3, dc4) (PRMS: gdb/12776)

=== gdb Summary ===

# of expected passes 9
# of known failures 2

gdb/testsuite/

Test inf-call of varargs of type _Complex.
* gdb.base/varargs.c (find_max_float_real): New.
(find_max_double_real, find_max_long_double_real): New.
* gdb.base/varargs.exp: Call these new added functions.
