I'd love to see -ffast-math in ldc.

Some timings on a 1st gen corei7 for floating-point heavy code 
(doubles):

gdc -frelease -fno-bounds-check -O3 -march=native
     27171ms

gdc -frelease -fno-bounds-check -Ofast -march=native
     16786ms

ldc2 -release -O5 -disable-boundscheck -mcpu=native
     35523ms

ldc2 -release -O5 -disable-boundscheck
     34864ms

ldc2 -release -O2 -disable-boundscheck
     34724ms

ldc2 -release -O1 -disable-boundscheck
     42365ms

ldmd2 -release -inline -noboundscheck -O
     31982ms


P.S. there's an overhead of about 4000ms in there from allocating 
memory and calls to fftw.
