[Bug bootstrap/21556] [4.0/4.1 Regression] ia64-hpux bootstrap fails on mainline, TLS failures on 4.0 branch

I'm now running the C testsuite with the before-and-after stage1 compilers to
see if that shows up any problems.

On 4.0 branch the patch doesn't cause bootstrap failure but there are a number
of new testsuite failures, all -milp32 only, which might show up with a
cross-compiler and indicate the source of this or a related problem.  All these
appeared between 20050512 and 20050514, and seem likely to be related to this patch.

(Also note that gcc.dg/tls/opt-9.c still fails for -milp32 although it now
passes for -mlp64.)

and several more following the same pattern.
