A side note: there are several places where we should use eat_line but instead
we now have explicit loops. I will take a scan through and find those while I
am at it. Just code clean-up.

For a reference, this is the patch I am testing:
Yes, this patch fixes stdarg failures from [1] with preliminary test:
FAIL: gcc.c-torture/execute/stdarg-1.c execution, -O3
This sequence makes no less than 2 calls memmoving 0 bytes:
vectorchar content;
content.resize(12);
From *0x0 no less!
On a 64 bit system, the effect is far less pronounced (25%), but on 32 bits,
this loop takes 2.3 seconds on a vanilla g++;
for(int n=0; n 1000; ++n) {

Ok, let's do something about this, likely just add a check in __copy_move (and
__copy_move_b), as suggested.

GCC will not bootstrap after the expand from tuples checkin because the pointer
extension code is wrong. If you compile gcc.dg/20020517-1.c you can see the
problem. This test compiled and ran before but now core dumps. The difference
in the generated assembly code is:
addp4 r14 = r12,

First round of regression hunting shows that r146781 (4/25/09) passes the
libjava like gcc 4.4.1 but r148013 (5/31/09) shows the additional 120+ libjava
failures.
