Patch to allow Ada to work with tree-ssa

[Richard Kenner]

    When that user upgrades their hardware, they say 'hey my *computer* is
    faster', not 'hey gcc is faster'.
    
    Their expenditure on new faster hardware does not get them faster
    development cycles, if gcc eats it all up.

Of course not.  And I'm hardly arguing in favor of compilers getting slower.
I'm just pointing out that if you're going to be making comparisons of the
state of things over a period measured in years, you also have to take into
account the change in available hardware during that period.
