Igor Kirillov 59a063d5c6 [ExpandMemCmp] Improve memcmp optimisation for boolean results (#71221) ...

This patch enhances the optimization of memcmp calls when only two
outcomes
are needed and comparison fits into one block, for example:

	bool result = memcmp(a, b, 6) > 0;

Previously, LLVM would generate unnecessary operations even when the
user of
memcmp was only interested in a binary outcome.
