Subject: vim-patch:8.1.0958: compiling weird regexp pattern is very slow

Problem:    Compiling weird regexp pattern is very slow.
Solution:   When reallocating post list increase size by 50%. (Kuang-che Wu,
            closes vim/vim#4012)  Make assert_inrange() accept float values.
https://github.com/vim/vim/commit/38f08e76acf7d21bb34cf8f79f0f82eb63cdc987

Omit changes to typval_compare()
because patch v8.0.1505 was not ported.
