Run StripDeadPrototypes as a final pass to ensure that the prototypes
for lifetime.start/end are removed.

Clang's implementation of C++ method pointers generates IR that uses
LLVM registers with struct type -- specifically, loads and stores of
struct values, and extractvalue instructions. See
lib/CodeGen/ItaniumCXXABI.cpp in Clang. Add a pass, ExpandStructRegs,
which expands out those uses.
Factor out a function from ExpandArithWithOverflow so that the two
passes can share some code.

This is a reapply of dc58e24a with one cleanup of a commented-out line in PromoteIntegers.cpp

This widens i1, i8 and i16 function arguments and return types.
Factor out RecreateFunction() helper function from existing PNaCl
passes since this is a reoccurring code fragment.

This reverts commit dc58e24a36836fc19c534bdcbef5152717a3c3fc.
That change broke the build of the sandboxed PNaCl translator.

It turned out that umul.with.overflow wasn't the only *.with.overflow
intrinsic usage introduced by Clang.
I knew that Clang's CGExprCXX.cpp generates umul.with.overflow for an
overflow check for C++'s "new Foo[]". The same code for handling "new
Foo[]" also generates uadd.with.overflow in some cases. This happens
if class Foo has a destructor or a delete[] operator that takes a size
argument. In those cases, the C++ ABI adds a "cookie" to the
allocation which contains the array's size.
Rename the pass to "ExpandArithWithOverflow" and rename files
accordingly.
Also enable the pass.

These meta-passes will be used to replace the pass lists that are
currently in the pnacl-ld.py driver script in the NaCl repo.
I've moved the comments across from pnacl-ld.py and added a couple
more comments for ExpandByVal and StripMetadata.
Fix the declaration of createResolveAliasesPass().
