Devang Patel 941ab37ea8 Use cast instead of dyn_cast. 
Update test to use multiple return value directly, instead of relying on -sretpromotion.

Duncan Sands 053c9871cd Revert r46393: readonly/readnone functions are no 
longer allowed to write through byval arguments.

Duncan Sands dc157a4f0a Invert this test, because it is wrong if we allow 
readonly functions to use byval parameters as local
storage (how much do we want this?).

Chris Lattner 4f6c81ac68 we don't have to make an explicit copy of a byval argument when 
inlining a function if we know that the function does not write
to *any* memory.  This implements test/Transforms/Inline/byval2.ll

Chris Lattner 908117bf69 When inlining a functino with a byval argument, make an explicit 
copy of it in case the callee modifies the struct.

Duncan Sands aa31b92508 When inlining through an 'nounwind' call, mark inlined 
calls 'nounwind'.  It is important for correct C++
exception handling that nounwind markings do not get
lost, so this transformation is actually needed for
correctness.

Duncan Sands b5a79d0eaa Make invokes of inline asm legal. Teach codegen 
how to lower them (with no attempt made to be
efficient, since they should only occur for
unoptimized code).

Duncan Sands 8e4847ee95 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...

Reid Spencer 6e87ec4351 For PR1319: 
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.

Reid Spencer d029c7e666 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.
