I remember I made a thread once that also was about getting aliases: http://forums.wowace.com/showthread.php?t=19736
The mentioned Wowpedia page for reference: http://wow.gamepedia.com/Lua_functions

local t = {}

for _, v1 in pairs( {math, string, table} ) do
	for k, v2 in pairs(v1)do
		t[v2] = k
	end
end

for k, v in pairs(_G) do
	if type(v) == "function" and t[v] then
		print(k, t[v])
	end
end

I think these are most of the aliases
There don't seem to be aliases for the bit functions
