add one more case of mismatched input/output constraints.
...
When the mismatch is due to a larger input operand that is
a constant, truncate it down to the size of the output. This
allows us to accept some cases in the linux kernel and elsewhere.
Pedantically speaking, we generate different code than GCC, though
I can't imagine how it would matter:
Clang:
movb $-1, %al
frob %al
GCC:
movl $255, %eax
frob %al

If the phi node was used by an unreachable instruction that ends up using
...
itself without going via a phi node then we could return false here in
spite of making a change. Also, tweak the comment because this method
can (and always could) return true without deleting the original phi node.
For example, if the phi node was used by a read-only invoke instruction
which is used by another phi node phi2 which is only used by and only uses
the invoke, then phi2 would be deleted but not the invoke instruction and
not the original phi node.

larger than GCC's code.
