96c3d2e2e7 Fix the 'have a framepointer' case, so that the frame pointer always points
to the old saved EBP.

clobber them by allocating other objects in the same space!

that will be responsible for the creation of MachineFunctions and will
be required by all MachineFunctionPass passes.

b663d76f86 Modularize implementation of LeakDetector into a typed template
implementation class. This makes the code simpler and allows for more
types to be added easily. It also implements caching for generic
objects (it was only available for llvm objects).

bb07ef97cf The prologue/epilogue related method calls have no reason to return a value,
make them return void.

This allows us to avoid some costly MBB.size() calls

cc42d2c3cc A target that doesn't support these intrinsics will still meet spec (the
intrinsic will always produce zero), but it will behave unexpectedly, so
warn like GCC does.

bc79471be1 Add next() and prior() iterator utility functions. Unlike std::advance
they do not modify the passed iterator but return a copy.

next(myIt) returns copy of myIt incremented once
next(myIt, n) returns copy of myIt incremented n times
prior(myIt) returns copy of myIt decremented once
prior(myIt, n) returns copy of myIt decremented n times

While at it remove obsolete implementation of mapped_iterator.

94f4f8ea10 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less
