Add IsDataEdge() and DataEdgeValue() helper functions.

This moves repetitive logic accessing data edges into its own header, and more strongly defines the notion of what a data edge is, enforcing the internal invariants. This will also be incorporated in optimized Cord iteration logic once CordRepConcat is totally removed from the Cord code.

Make it clear that the probability function given for the zipf distribution is unnormalized, i.e., sum(p(x) for x = 0..k) != 100%.

Quoting Section 7 of the paper cited in the comments, where this formula comes from (emphasis mine): "We will consider the two parameter generalization as defined in Dagpunar [1988] with the *unnormalized* probability function ..."

Support symbolization on PA-RISC

Null out supervisor bits in PA-RISC addresses before symbolizing, and
handle function descriptor tables correctly.

Change symbolize_test.cc to use 32-bit aligned addresses, allowing that
test to pass on PA-RISC.
