5d0f68134e Add a default debug location object to the Machine Function. It's used to emit a default debugging label at the beginning of a function.

dfdacee2ab Generate these labels when we're in "fast" mode, not simply when we're no in 
"optimize-for-size" mode.

4a359ea2d5 Use DEBUG() instead of passing *DOUT to WriteAsOperand, 
since the latter just passes a null reference when
debugging is not enabled.

the symlink.  This lets clang find its headers when invoked through

95c5d0fb0a In theory the aliasee may have dead constant users 
here.  Since we only do the transform if there is
one use, strip off any such users in the hope of
making the transform fire more often.

f5a309e989 Use a sign-extend instead of a zero-extend when promoting a 
trip count value when the original loop iteration condition is
signed and the canonical induction variable won't undergo signed
overflow. This isn't required for correctness; it just preserves
more information about original loop iteration values.

Add a getTruncateOrSignExtend method to ScalarEvolution,
following getTruncateOrZeroExtend.

d6b7a242d3 Add support to the JIT for true non-lazy operation. When a call to a function 
that has not been JIT'd yet, the callee is put on a list of pending functions
to JIT.  The call is directed through a stub, which is updated with the address
of the function after it has been JIT'd.  A new interface for allocating and
updating empty stubs is provided.

Add support for removing the ModuleProvider the JIT was created with, which
would otherwise invalidate the JIT's PassManager, which is initialized with the
ModuleProvider's Module.

Add support under a new ExecutionEngine flag for emitting the infomration 
necessary to update Function and GlobalVariable stubs after JITing them, by
recording the address of the stub and the name of the GlobalValue.  This allows
code to be copied from one address space to another, where libraries may live
at different virtual addresses, and have the stubs updated with their new
correct target addresses.

d2067fd730 Fix a corner case in the new indvars promotion logic: if there 
are multiple IV's in a loop, some of them may under go signed

exit condition doesn't. Restrict sign-extension-elimination
and zero-extension-elimination to only those that operate on
the original loop-controlling IV.

60f8a63e25 Add a method to ScalarEvolution for telling it when a loop has been 
modified in a way that may effect the trip count calculation. Change
IndVars to use this method when it rewrites pointer or floating-point
induction variables instead of using a doInitialization method to
sneak these changes in before ScalarEvolution has a chance to see
the loop. This eliminates the need for LoopPass to depend on
ScalarEvolution.
