size for SymTridiagonal returning incorrect value
add Diagonal AbstractMatrix
fix #2667, dump on Exprs
also avoid dumping whole type hierarchy on dump() (only in xdump)
Merge branch 'master' of github.com:JuliaLang/julia
optimization: hoist array metadata access out of loops (sometimes)

Update macro syntax in the doc.
removed Vector * Diagonal and Vector / Diagonal, as not defined for Matrix
Slight tweaking of the macro syntax documentation.
