Improved popFront, gdc as before (-frelease -finline-functions -fweb -O3):

ascii 22.69%:  old [2 secs, 449 ms, 248 μs, and 7 hnsecs], new [555 ms,
718 μs, and 3 hnsecs]
uni   42.52%:  old [3 secs, 879 ms, 380 μs, and 7 hnsecs], new [1 sec,
649 ms, 387 μs, and 4 hnsecs]

For comparison, on the same machine with dmd -release -O -inline,

ascii 118.23%: old [1 sec, 754 ms, 449 μs, and 2 hnsecs], new [2 secs,
74 ms, 197 μs, and 8 hnsecs]
uni   86.82%:  old [4 secs, 413 ms, 167 μs, and 8 hnsecs], new [3 secs,
831 ms, 569 μs, and 1 hnsec]

(The machine is an old 32-bit Athlon XP 3000+ ("Barton"))

When gdc finishes building on my 64-bit box I can run timings on that, 
but it's a crappy underpowered emachine/acer, so any results may say 
less about any 32/64 bit differences and more about what happens when 
you buy a $250 computer at Walmart.
