This is with the 20050130 snapshot on ia64-unknown-linux-gnu,
-O3 and with flag_complex_divide_method = 1. The files slasy2.f
and dlasy2.f are compiled with -O0, to get around PR 18977.

This is looking pretty good, on the whole. The DES and DSX failures
are a bit suspect:
N= 5, IWK= 1, seed= 100,2082, 33, 613, type 17, test( 7)= 0.450E+16
DDRVES: DGEES1 returned INFO= 6.
N= 5, JTYPE= 17, ISEED=( 100, 2082, 33, 613)
N= 5, IWK= 2, seed= 100,2082, 33, 613, type 17, test( 7)= 0.450E+16
DES: 2 out of 3264 tests failed to pass the threshold
*** Error code from DGEES = 6
DGET24: DGEESX1 returned INFO= 6.
N= 5, JTYPE= 17, ISEED=( 100, 2082, 33, 613)
N= 5, IWK= 2, seed= 100,2082, 33, 613, type 17, test( 7)= 0.450E+16
DSX: 2 out of 3494 tests failed to pass the threshold
The condition numbers are quite high. There may or may not be an
optimizer bug hidden there. I'll look around if I can isolate
anything, and open a separate PR then.
