utils/sort_includes.py. I clearly haven't done this in a while, so more changed than usual. This even uncovered a missing include from the InstrProf library that I've added. No functionality changed here, just mechanical cleanup of the include order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225974 91177308-0d34-0410-b5e6-96231b3b80d8

/// Pass managers have ()s describing the nest structure of passes. All passes

/// are comma separated. As a special shortcut, if the very first pass is not
|
|
/// a module pass (as a module pass manager is), this will automatically form
|
|
/// the shortest stack of pass managers that allow inserting that first pass.
|
|
/// So, assuming function passes 'fpassN', CGSCC passes 'cgpassN', and loop passes
|
|
/// 'lpassN', all of these are valid:
|
|
///
|
|
/// fpass1,fpass2,fpass3

/// cgpass1,cgpass2,cgpass3

///
|

/// module(function(fpass1,fpass2,fpass3))

/// module(cgscc(cgpass1,cgpass2,cgpass3))

/// This shortcut is especially useful for debugging and testing small pass
|

/// combinations. Note that these shortcuts don't introduce any other magic. If
