Same std::thread split as exhaustive32_midpoint; preserves each test's existing
failure behavior (abort for exhaustive32, stop-flag for exhaustive32_64).

Add a 4-digit SWAR follow-up to loop_parse_if_eight_digits (clang)
...
After the 8-digit SWAR block loop, consume a remaining 4-7 digit run in one
read4_to_u32 + parse_four_digits_unrolled step instead of byte-by-byte (reusing
the existing 4-digit helpers). The parsed result is identical; this is purely a
faster way to consume the same digits.
Gated to clang: on gcc the extra 4-digit check regresses inputs whose remainder
is < 4 digits (e.g. the 17-digit fraction of uniform [0,1] -> -3% on 'random'),
because the check becomes pure overhead there; clang does not show that.
m8g.metal-24xl (Graviton4), -O3 -march=native, simple_fastfloat_benchmark,
from_chars->double, clang 18, base vs patch back-to-back (2 samples):
canada.txt +11.7%, mesh.txt +7.4%, random ~flat. No regression.

Unroll the integer-part digit scan (straight-line for the common 1-5 digit case)
...
parse_number_string scans the integer part one byte at a time in a while loop,
while the fraction already uses the 8-digit SWAR loop. Most integer parts are
1-5 digits, so the loop back-edge dominates. Peel the first five iterations into
nested ifs, falling through to the original while for longer runs. Semantics are
identical (i = 10*i + digit, advancing p); no behavior change.
AWS m8g.metal-24xl (Graviton4), -O3 -march=native, simple_fastfloat_benchmark,
from_chars->double. base vs patch measured back-to-back, mean of 2 runs:
canada: gcc +3.1%, clang +2.8%
mesh: gcc +5.4%, clang +5.1%
random: ~flat (1-digit integer part)
No regression; gcc and clang agree.
Alternatives benchmarked and rejected: reusing loop_parse_if_eight_digits for the
integer part regressed 5-8% (integer parts are too short for 8-digit SWAR setup);
a counted for(k<5) loop matched on gcc but clang optimized it worse (canada -0.9%).
The explicit peel is the only form solidly positive on both compilers.
