raw_ostream doesn't try to do its own error handling.
Also, close the raw_ostream before checking for errors so that any
errors that occur during closing are caught by the manual check.

bugpoint does "Running the code generator to test for a crash" this
gets you a crash if llc goes into an infinite loop or uses up vast
amounts of memory.

isn't ideal if we want to be able to use another object file format.
Add a createObjectStreamer() factory method so that the correct object
file streamer can be instantiated for a given target triple.

The revision history for this function is interesting, with multiple layers of
wrongness being introduced one at a time.
This fixes a weird issue where bugpoint -run-llc would suddenly exit 13 half way
through isolating a miscompilation.

and the others use the regular addPassesToEmitFile hook now, and
llc no longer needs a bunch of redundant code to handle the
whole-file case.

string of features for that target. However LTO was using that string to pass
into the "create target machine" stuff. That stuff needed the feature string to
be in a particular form. In particular, it needed the CPU specified first and
then the attributes. If there isn't a CPU specified, it required it to be blank
-- e.g., ",+altivec". Yuck.
Modify the getDefaultSubtargetFeatures method to be a non-static member
function. For all attributes for a specific subtarget, it will add them in like
normal. It will also take a CPU string so that it can satisfy this horrible
syntax.

that was causing PC-relative branch targets to be
evaluated incorrectly. Also added support for
checking operand values to the llvm-mc tester.

std::vector<CallGraphNode*>. No functionality change,
but now we have a much tidier interface.

native linking export files, including running sed to prepend underscores
on darwin, and make use of it in libLTO and libEnhancedDisassembly.
Remove the leading underscores from library export files so that they
work with the new EXPORTED_SYMBOL_FILE support.

code. It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.
Also removed hacky #define-controlled initialization
of targets in edis. If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.
