ghc -fasm declared not too shabby

[Donald Bruce Stewart]

Got some initial nobench numbers for ghc head -fvia-C versus -fasm, on
amd64:

    http://www.cse.unsw.edu.au/~dons/nobench/x86_64/results.html

Overall all of nobench, ghc -fasm averages 3% slower. Not too shabby!
There's some wider variation on the microbenchmarks in the imaginary
class:

    one case 20% faster, another 30% slower, average 2% slower.

On real programs though, 3% slower on average.
The big benefit of course, no perl, no gcc and faster compilation times.
