Port, board and/or hardware

unix, coverage build, x86_64 linx

MicroPython version

v1.27.0-preview-32-g141f7d0c35

Reproduction

1. Build the unix "longlong variant"
2. in the repl, type int("-9223372036854775808")
3. in the repl, type -9223372036854775808

Expected behaviour

The integer constant can be parsed.

Observed behaviour

Each case results in OverflowError: result overflows long long storage. However, they're slightly different:

• the first one reaches mp_parse_num_integer with the string argument "-9223372036854775808". This may be relatively straightforward to fix.
• the second reaches mp_parse_num_integer with the string argument "9223372036854775808" (no leading "-"). Fixing this would require making the byte compiler recognize unary negation of an integer constant as special.
