[builtins] Rewrite uri.js as builtin functions.
...
Rewrite decodeURI and decodeURIComponent as builtin functions
and install them in the bootstrapper.
Delete unused runtime functions:
- TruncateString
- NewString
- OneByteSeqStringGetChar
- OneByteSeqStringSetChar
- TwoByteSeqStringGetChar
- TwoByteSeqStringSetChar
Add regression test for decoding large strings. Clusterfuzz detected
a problem with %TruncateString, see
https://bugs.chromium.org/p/chromium/issues/detail?id=612109#c6
This is automatically fixed by this rewrite because %TruncateString
is deleted anyways.
Crude benchmark on 585 decodeURI and decodeURIComponent tests
averaged over five runs:
* builtin functions
real 0m9.69s
user 2m39.8816s
sys 0m12.6398s
* JS functions calling into the runtime e.g., for %TruncateString
real 0m11.0598s
user 3m6.7026s
sys 0m13.5756s
