In collator and localeCompare, we have an incorrect optimization
for zero length string that compare the length and ignore the
fact some non zero length string could be considered as equal to
a zero length string because the content are all ignoreable.
Took out this incorrect optimization with test cases.
The regression is introduced in
6fbb8bc806 which first appeared in 97.0.4665.0

This fast path works for ASCII-only strings and is similar to the
existing fast-path in C++. Important differences:
- The locale check is done at Turbofan optimization time instead of
at runtime
- Use tables of size 256 instead of 128 to save a bounds-check when
handling one-byte strings.
- It first performs an equality check that's optimized for detecting
inequality quickly by comparing the strings from both ends. If the
equality check succeeds, we are done. Otherwise chances are high
that the strings differ according to collation level L1 already.
Therefore, we first do an L1 check and perform the L3 check
only when L1 didn't find a difference. This is based on the assumption
that few strings are identical except for different capitalization.
- Use the Torque version of string flattening instead of the runtime
version.

Certain collators and subject strings may take this new fast
path without calling into the (slow) ICU comparison functions.
This CL can be roughly split into three topics:
1. The fast path check, precomputed and implemented as a whitelist
on the current locale string.
2. The actual fast path, which checks subject string eligibility
and performs L1 and L3 collation weight comparisons all in one pass.
3. Resuming from an aborted fast-path into the generic path.

This is a temp fix to throw instead of DCHECK in debug build.
The correct fix depends on the landing of
https://github.com/unicode-org/icu/pull/1762
Once that land I will cherrypick into chrome to fix the function correctly.
But the current (before this CL) behavior is not harmful in release build.
It basically does not do the max nor min just return itself.
