4354953b4f Bug 1118486 - Part 1: Use = delete instead of MOZ_DELETE directly; r=Waldo 
Most of this patch (with the exception of dom/bindings/Codegen.py) was
generated by the following bash script:

#!/bin/bash

function convert() {
echo "Converting $1 to $2..."
find . ! -wholename "*nsprpub*" \
       ! -wholename "*security/nss*" \
       ! -wholename "*/.hg*" \
       ! -wholename "*/.git*" \
       ! -wholename "obj-*" \
         -type f \
      \( -iname "*.cpp" \
         -o -iname "*.h" \
         -o -iname "*.cc" \
         -o -iname "*.idl" \
         -o -iname "*.ipdl" \
         -o -iname "*.ipdlh" \
         -o -iname "*.mm" \) | \
    xargs -n 1 sed -i -e "s/\b$1\b/$2/g"
}

1813ae2d33 Bug 867348 - Part 2: Apply MOZ_NO_ARITHMETIC_EXPR_IN_ARGUMENT to CheckedInt's constructor; r=jrmuizel,cpearce 
Note that the analysis currently just looks at the AST subtree of the
function call site and is therefore unable to correctly deal with cases
such as the last two hunks of the change to OggCodecState.cpp.  Fixing
the analysis to deal with that would be very difficult, so we currently
adjust the code so that it compiles.  The first hunk in that file though
is a real bug that this analysis found.
