Subject: | [PERF] ≥ and ≤ are 36x slower than Texas version; ≠ is 15x slower |

I'd expect the fancy Unicode versions of <=, >=, and != to perform equally well, instead the
≥ and ≤ are 36x slower than their Texas companions and ≠ is 15x slower.
Here's the timings for >= vs ≥:
m: my $x = rand; for ^1000_000 { $ = $x >= 1_000_000_000_000 }; say now - INIT now;
rakudo-moar 43c176: OUTPUT: «0.74663187»
m: my $x = rand; for ^1000_000 { $ = $x ≥ 1_000_000_000_000 }; say now - INIT now;
rakudo-moar 43c176: OUTPUT: «(timeout)»
m: my $x = rand; for ^1000_0 { $ = $x ≥ 1_000_000_000_000 }; say now - INIT now;
rakudo-moar 43c176: OUTPUT: «0.2661272»
m: say 0.2661272*100 / 0.729002
rakudo-moar 43c176: OUTPUT: «36.505689»
