intead request a nice declarative interface.
Cleans up an IMHO ugly wart.

target directories themselves. This also means that VMCore no longer
needs to know about every target's list of intrinsics. Future work
will include converting the PowerPC target to this interface as an
example implementation.

"getOrInsertFunction" in that it either adds a new declaration of the global
and returns it, or returns the current one -- optionally casting it to the
correct type.
- Use the new getOrInsertGlobal in the stack protector code.
- Use "splitBasicBlock" in the stack protector code.

use raw_ostream instead of std::ostream. Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).
Other interesting changes:
1) This makes Value::print be non-virtual.
2) AP[S]Int and ConstantRange can no longer print to ostream directly,
use raw_ostream instead.
3) This fixes a bug in raw_os_ostream where it didn't flush itself
when destroyed.
4) This adds a new SDNode::print method, instead of only allowing "dump".
A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream
versions.
This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.

of a std::string. This avoids copying the string to the heap in common
cases. Patch by Pratik Solanki!

object is always constant. As such, evaluate it at compile time instead of storing
it as an ivar in SymbolTableListTraits. This shrinks every SymbolTableListTraits
ilist by a word, shrinking BasicBlock from 44->40 bytes, Function from 96->88 bytes,
and Module from 60->52 bytes.

of two. This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60). On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.

Clean up the Module::getFunction interface. getMainFunction and
getNamedFunction are now gone. Just use getFunction instead.

This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

Make the Module's dependent library use a std::vector instead of SetVector
adjust #includes in .cpp files because SetVector.h is no longer included.

Remove the setEndiannes and setPointerSize methods. These are now set
through the setDataLayout method.

Take an incremental step towards type plane elimination. This change
separates types from values in the symbol tables by finally making use
of the TypeSymbolTable class. This yields more natural interfaces for
dealing with types and unclutters the SymbolTable class.

rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

a better encoding of the targets data layout, rather than trying to guess it
from the endianness and pointersize like before.

Remove Function::aiterator and Module::giterator typedefs (and const versions)
as they should have been removed when abegin/gbegin were removed. Thanks to
alkis for bringing this to my attn.

pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

Rename argument iterators arg_* instead of a*
Remove global variable iterators global_* instead of g*.
Keep the old names for temporary compatibility.
