Simplify atoi*/strto* for signed integers.
Make the cost of strto<signed> closer to the cost of strto<unsigned>
by removing an `if` from the inner loop. Previously a signed conversion
cost 10ns more than an unsigned one.
After:
BM_inttypes_strtoimax 81 ns 81 ns 8603362
BM_inttypes_strtoumax 78 ns 78 ns 8967174
BM_stdlib_strtol 81 ns 81 ns 8685537
BM_stdlib_strtoll 81 ns 81 ns 8685481
BM_stdlib_strtoul 78 ns 78 ns 8962569
BM_stdlib_strtoull 78 ns 78 ns 8972023
Bug: N/A
Test: ran tests, benchmarks
