5b82f780f8 Allocate objects on the stack if they (a) don't have a destructor, and 
(b) don't override the delete operator (on top of the regular conditions for
stack allocation that also apply to arrays, structs, etc.).
The "no destructor" clause is not strictly necessary, but calling them at the
right time would be tricky to say the least; it would involve, among other
things, "manually" inserting a try-finally block around anything that might
throw exceptions not caught in the current function.

Note: objects with custom new operators are automatically ignored because they
don't use the regular allocation runtime call, so there's no need to pay special
attention to them.

adf1fd4d44 Work around an LLVM bug by not referring to globals from metadata. This was 
only used for consistency checking anyway.
For the LLVM bug, see http://llvm.org/PR4180 / http://llvm.org/PR4046

cf0b8936ce Factor out the code to find gcc, and add a command-line option to override the 
default executable name.
This should help cross-compilation by allowing a cross-gcc to be specified from
the configuration file instead of only through the CC environment variable.

262ef97945 There's an issue with LLVM metadata support; it triggers an assert when trying 
to generate asm for code with metadata globals.
This new pass is used as a workaround: it strips metadata from the module before
it reaches the code generator.
Obviously, this is disabled if LLVM doesn't support metadata.

cff0f1f446 Implement another D-specific pass: -dgc2stack 
This one promotes GC allocations to stack memory when it can determine it's safe
to do so.
Not all GC calls are recognized yet (in fact only one *is* recognized for now).
Needs metadata, so disabled for LLVM versions that don't support it.

da4450d2f5 Make sure this still compiles after LLVM r70437, which introduces a 
specialization for command-line option template parser<char> which does the
wrong thing for us...

b9849d86b6 Update codegen to (hopefully) work correctly with newer LLVM trunk, where 
there's no longer a Fast flag. (It has been replaced by an optimization level)
Untested because I haven't compiled that recent an LLVM yet :).

0df1e34eb2 Implement first D-specific optimization pass: -simplify-drtcalls. 
It uses the machinery of the standard -simplify-libcalls pass, but optimizes
calls to the D runtime instead of calls to C libraries.

At the moment, these optimizations are implemented by this pass:
 - Avoid the runtime call for `arr.length = newlen` if it can determine that
   the new length isn't longer than the old one.
 - Ditto for `cast(T[]) arr` if it will clearly always succeed.
   (e.g. if the length of the original array is zero, or if the old element
   size is a multiple of the new element size)

f712c48312 Check in some old changes to the binding, from before I had commit access. 
- Add bindings for InsertValue and ExtractValue
 - Updates to use new APIs where they were renamed or removed.
 - Add generic error messages if LLVM didn't provide one.
 - Enable typesafe variadic arguments for GetGEP.
