% autoconf -o ../configure

This changes facilitaties the following:
1) It should be easier to incorporate new autoconf macros.
2) It allows for conversion to Automake (should we ever desire it).

Use getFileSize() instead of sys/stat.h directly

Use new getFileSize function.  Eliminate some using directives.  Reorder #includes a bit

Add new method

Add a -disable-opt flag to gccas, so that we can use  -Wa,-disable-opt just
like -Wl,-disable-opt

Further revisions of the FDHandle idea.  In this version we use ownership
semantics that are the same as those used by std::auto_ptr.  This allows
copying of FDHandle's, but copying transfers ownership.

Add a new class useful for providing fully materialized modules to ExecutionEngine's

Allow C++ programs to end in .cc.  This allows C++ test programs in the
test suite to compile.

Add trivial exception specs to produce better code since the methods cannot
be inlined.

Factor FDHandle out of the bytecode reader into the FileUtilities.h support
routines.

implement new getToken function

What do you know, we actually do accomplish some things around here :)

Clean up a lot of the code I added yesterday by exposing the IntrinsicLowering
implementation from the TargetMachine directly.

Reserve ECX and EDI instead of EBX and EDI. Since EBX is a callee
saved register it has a longer free range than ECX (which is defined
every time there is a fnuction call) which makes ECX a better register
to reserve.
