vector_algorithms.cpp, *minmax*: invert the condition to improve *_element cases a bit more

[Alex Guteniev (AlexGuteniev)]

The possibility was realized when working on #4384.

I observed that the compiler swaps branches to make the _Minmax loop more local.
Applying the same change to the _Minmax_element loop gives significant improvement: 1.6 or 1.8 times for some cases.
Also made that change to _Minmax loop to maintain consistency (with both its counterpart and how it being compiled).
