output so that grep lines in the tests don't unintentionally match
strings in the input filename.

beyond their associated static array type.
I believe that this fixes a legitimate bug, because BasicAliasAnalysis
already has code to check for this condition that works for non-constant
indices, however it was missing the case of constant indices. With this
change, it checks for both.
This fixes PR4267, and miscompiles of SPEC 188.ammp and 464.h264.href.

couldn't ever be the return of call instruction. However, it's quite possible
that said local allocation is itself the return of a function call. That's
what malloc and calloc are for, actually.

The problematic part of this patch is that we were out of attribute bits,
requiring some fancy bit hacking to make it fit (by shrinking alignment)
without breaking existing users or the file format.
This change will require users to rebuild llvm-gcc to match llvm.

parallel, allowing it to decide that P/Q must alias if A/B
must alias in things like:
P = gep A, 0, i, 1
Q = gep B, 0, i, 1
This allows GVN to delete 62 more instructions out of 403.gcc.

actual definition is slightly less strict (for now).
No changes to the bitcode reader/writer, asm printer or verifier were needed.

never escapes, the pointers can't alias. This implements PR2436

instruction guarantees it. It also changes difference between offsets to
absolute value of this difference in the condition.

Remove && from the end of the lines to prevent tests from throwing run
lines into the background. Also, clean up places where the same command
is run multiple times by using a temporary file.

test system a different interface function name.
