Vyacheslav Egorov 375b32d621 [vm/compiler] Canonicalize more intermediate constants in IL. 
* when building IL from Kernel use canonical double representation
instead of allocating new double objects;
* in constant propagation canonicalize immutable primitive constants
(strings, mints and doubles) before replacing instruction with its
constant value;

This relands 5909932d38 with the part
that was causing timeouts on flutter_test reverted.

See https://github.com/dart-lang/sdk/issues/32904 for more details.
