Upgrade mimalloc to 1.8.7
Ниже описал существенные изменения в поведении, которые я заметил (в сравнении с версией 1.7.2, которая лежит в контрибах сейчас)
Полный changelog можно посмотреть в [readme.md](http://readme.md)
* Поменялся дефолт у [опции](https://github.com/microsoft/mimalloc/blob/9cae0d31cd28476664dbaa6e4e6940b9d900842a/src/options.c#L109), определяющей то, как неиспользуемая память возвращается в систему. В старых версиях по умолчанию использовался madvise с флагом MADV_FREE, в свежих версиях же используется MADV_DONTNEED. Это может вызвать неожиданные изменения (в худшую сторону) на графиках потребляемой анонимной памяти (), хотя по факту потребление должно быть \+- одинаковым
* Алгоритм работы аллокатора претерпел некоторые изменения. Например, мы споткнулись об то, что в новой версии mimalloc выделяет себе 1Gb (размер задается [опцией](https://github.com/microsoft/mimalloc/blob/2765ec93026f445cad8f38e6b196dd226a1f6e61/src/options.c#L87)) памяти при первой же аллокации. Само по себе это мало на что влияет, но неприятности могут случиться, если звать в начале программы mlockall
