Support per-function alignment information #164
Description
The LLVM Language Reference specifies that a function definition can have an explicit alignment ([align N]), but llvm-pretty's Define data type does not have any place to store explicit alignment information. We should do so and update llvm-pretty-bc-parser to parse it accordingly. See here for the corresponding code in LLVM that parses explicit function alignment—it uses field 5, which llvm-pretty-bc-parser currently ignores.
