Query: string.Concat gives different results than L2O for some types

[maumar]

query:

from g in gs
from m in ms
orderby g.Nickname, m.Id
select new
{
	HasSoulPatch = string.Concat("HasSoulPatch " + g.HasSoulPatch, " HasSoulPatch"),
	Rank = string.Concat("Rank " + g.Rank, " Rank"),
	SquadId = string.Concat("SquadId " + g.SquadId, " SquadId"),
	Rating = string.Concat("Rating " + m.Rating, " Rating"),
	Timeline = string.Concat("Timeline " + m.Timeline, " Timeline")
}

result:

{ HasSoulPatch = HasSoulPatch 1 HasSoulPatch, Rank = Rank 1 Rank, SquadId = SquadId 1 SquadId, Rating = Rating 2.1 Rating, Timeline = Timeline 0002-01-02 10:00:00.0000000 +01:30 Timeline }

l2o:

{ HasSoulPatch = HasSoulPatch True HasSoulPatch, Rank = Rank Corporal Rank, SquadId = SquadId 1 SquadId, Rating = Rating 2.1 Rating, Timeline = Timeline 1/2/0002 10:00:00 AM +01:30 Timeline }

We may need to consider cases like this when working on the 3.0 behavior for funcletization (#12795) but it may also be just a case of translating to SQL Server appropriately using case to go from the store representation to the string we want.
