bitint: Fix build [PR121413]
Sorry, my bootstrap failed last night because of this, I've fixed it
up and it bootstrapped/regtested fine overnight, but in the morning
forgot to adjust the patch before committing.
Without this there is
.../gimple-lower-bitint.cc:7678:36: error: comparison of integer
expressions of different signedness: ‘unsigned int’ and ‘int’
[-Werror=sign-compare]
7678 | if (min_prec > limb_prec && abi_limb_prec >
limb_prec)
