    cmd/compile: remove rtype.ptrToThis · 30f93f09
    David Crawshaw authored
    Simplifies some code as ptrToThis was unreliable under dynamic
    linking. Now the same type lookup is used regardless of execution
    mode.
    
    A synthetic relocation, R_USETYPE, is introduced to make sure the
    linker includes *T on use of T, if *T is carrying methods.
    
    Changes the heap dump format. Anything reading the format needs to
    look at the last bool of a type of an interface value to determine
    if the type should be the pointer-to type.
    
    Reduces binary size of cmd/go by 0.2%.
    For #6853.
