merged to_index and indices into to_index
restrict some checkbounds signatures

A signature such as checkbounds(A::AbstractMatrix, I, J) was always
superseded by checkbounds(A::AbstractArray, I::Union(Real,AbstractArray)...)
simplify some checkbounds code

bitarray: full multidimensional bounds checks

Fix #2495
improved error messages, removed function names
Enable reporting to status.julialang.org
Consistently use quotes in parsing errors

Use quotes around parsed expressions to make understanding
messages easier.
Changed the printing of MethodError

MethodError printed "no method f(DataType)" for if it couldn't find a
method for the concrete datatype, eaven tough there were methods
available for other datatypes. This pathch changes the printing from
DataType to Type{MyType} instead.
