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.

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

68300db685 Add support for fopen/fclose. Specifically with fopen, we were marking all of the
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.

allowed in invoke instructions.  Thus, if we are inlining a call to an intrinsic
