idk performance nor compatibility, but it doesn't use EVAL

Eliminate p6decontrv ops caused by `*_u` ops

Otherwise `my uint $a; sub foo { $a = 0 }` gives
  `===SORRY!===
p6decontrv expects a QAST::WVal as its first child`.

Give .chomp the possibility to specify a needle

Basically:
   say "foobar".chomp("bar"); # foo
   say "foobar".chomp("baz"); # foobar		 11:02

japhb MasterDuke, nine: Looks like Digest still doesn't work at HEAD. Updated gist.github.com/japhb/68dded3c8576...fee0c2ff79 (-145 is Rakudo before the p6decontrv fix, -161 is after; now it looks like a uint problem.) 21:04
MasterDuke "Cannot unbox negative bigint into native unsigned integer" i wonder if it's doing something wrong that just happened to work before 21:07

MasterDuke m: use nqp; my str $s = (100..1_000).pick.Str; my int $i; my $n = now; $i = $s for ^10_000_000; say now - $n; say $i 21:13

MasterDuke a pretty simple change just about halves ^^^ runtime and gets rid of 10m temporary allocations, and i think it should be not too difficult to get even faster 21:14
and in a related question, wouldn't it be convenient for MVMStrings to both know their size and be null terminated? then, depending on encoding of course, the storage could be passed directly to C functions 21:17
guess it depends on how frequently we actually call C functions on strings to determine if the extra overhead (space, code complexity, etc) is worth it 21:19
but iirc, that's how D does it. or maybe C#?
oh, that would have made more sense over in #moarvm 21:24
