Some of these functions take some extraneous arguments, e.g. EltSize,
Offset, which are computable from the Type and DataLayout.
Add some asserts to ensure that the computed values are consistent
with the passed-in values, in preparation for eliminating the
extraneous arguments. This also asserts that the Type is an Array for
the calls named "Array" and a Struct for the calls named "Struct".
Then, correct a couple of errors:
1. Using CreateStructGEP on an array type. (this causes the majority
of the test differences, as struct GEPs are created with i32
indices, while array GEPs are created with i64 indices)
2. Passing the wrong Offset to CreateStructGEP in TargetInfo.cpp on
x86-64 NACL (which uses 32-bit pointers).

The tests that failed on a windows host have been fixed.
Original message:
Start setting dso_local for COFF.
With this there are still some GVs where we don't set dso_local
because setGVProperties is never called. I intend to fix that in
followup commits. This is just the bare minimum to teach
shouldAssumeDSOLocal what it should do for COFF.

On targets which use the MSVCRT, setjmp is a macro which expands to
_setjmp or _setjmpex.
_setjmp and _setjmpex have a secret, hidden argument which is not listed
in the function prototype on X64 and WoA. This hidden argument always
seems to be the frame pointer.
_setjmpex isn't used on X86, _setjmp is magically replaced with a call
to _setjmp3. The second argument is zero for 'normal' setjmp/longjmp
pairs, otherwise it is a count of additional variadic arguments. This
is used when setjmp appears inside of a try or __try.
It is not safe to use a pointer to setjmp because _setjmp, _setjmpex and
_setmp3 are not compatible with setjmp.
