fields. If so, it can't be a global constant.

representing variables whose type must be inferred
from the way they are used.  Functions without debug
information now return UnknownAnyTy and must be cast.

Variables with no debug information are not yet using
UnknownAnyTy; instead they are assumed to be void*.
Support for variables of unknown type is coming (and,
in fact, some relevant support functions are included
in this commit) but will take a bit of extra effort.

The testsuite has also been updated to reflect the new
requirement that the result of printf be cast, i.e.

expr (int) printf("Hello world!")

by non-CMP expressions.  The executable test case (129821) would test
this as well, if we had an "-O0 -disable-arm-fast-isel" LLVM-GCC
tester.  Alas, the ARM assembly would be very difficult to check with
FileCheck.

The thumb2-cbnz.ll test is affected; it generates larger code (tst.w
vs. cmp #0), but I believe the new version is correct.
