f1d84a5096 perf: use dsimp := false in split tactic and while proving equation theorems 
It is just a waste in these two cases.

It now takes 0.78 secs to process example on issue #1287.

dba1f79170 feat: improve isDefEq for projections 
When solving `a.i =?= b.i`, we first reduce `a` and `b` without using
delta reduction. If at least one become a structure, we reduce the
projection. Otherwise, we try to solve `a =?= b`, only reduce `a.i`
and `b.i` if it fails.

2a940dd4ae feat: add Expr.collectFVars, LocalDecl.collectFVars, Pattern.collectFVars, and AltLHS.collectFVars 
They are all in `MetaM`.

These are helper functions for issue #1237. We need to "cleanup" the
local context before trying to compile the match-expression.

8311c88fd0 refactor: extract methods from Lean.Meta.transform 
Lean.Meta.transform is created with a series of recursive
visit functions. However these visit functions are useful
on their own outside of transform for traversing expressions.

This commit moves the visit functions outside the main function.
