Benedikt Meurer 63345e68f8 [turbofan] Remove CheckSmi from String.fromCodePoint() lowering. 
The CheckSmi in String.fromCodePoint() is unnecessary and even leads to
unnecessary deoptimizations, since the CheckBounds already does the
right thing, plus it also handles HeapNumbers (in Signed32 range) and
properly identifies zeros.
