Fix a nasty bug (PR3550) where the inline pass could incorrectly mark
...
calls with the tail marker when inlining them through an invoke. Patch,
testcase, and perfect analysis by Jay Foad!

Do not inline functions with (dynamic) alloca into
...
functions that don't already have a (dynamic) alloca.
Dynamic allocas cause inefficient codegen and we shouldn't
propagate this (behavior follows gcc). Two existing tests
assumed such inlining would be done; they are hacked by
adding an alloca in the caller, preserving the point of
the tests.

Let some more tests ignore expected output on stderr.

Also, use > %t instead of -o %t for output in one test since that also works
when %t already exists.

Make instcombine promote inline asm calls to 'nounwind'
...
calls. Remove special casing of inline asm from the
inliner. There is a potential problem: the verifier
rejects invokes of inline asm (not sure why). If an
asm call is not marked "nounwind" in some .ll, and
instcombine is not run, but the inliner is run, then
an illegal module will be created. This is bad but
I'm not sure what the best approach is. I'm tempted
to remove the check in the verifier...
