* Removed test/lib/llvm.exp - it is no longer needed
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
left in the test suite so this code is no longer required. test/lit.cfg is
now much shorter and clearer
* Removed a lot of duplicate code in lit.local.cfg files that need access to
the root configuration, by adding a "root" attribute to the TestingConfig
object. This attribute is dynamically computed to provide the same
information as was previously provided by the custom getRoot functions.
* Documented the config.root attribute in docs/CommandGuide/lit.pod

is narrower than the shift register. Doing an anyext provides undefined bits in
the top part of the register.

and "save_volatiles" correctly. This completes the custom calling convention
functionality changes for the MBlaze backend that were started in 121888.

1. A delay slot filler that searches for valid instructions
to fill the delay slot with. Previously NOPs would always
be inserted into delay slots.
2. Support for MC based instruction printer added.
3. Support for MC based machine code generation and ELF
file generation. ELF file generation does not yet
completely work as much of the ELF support infrastructure
is still x86/x86-64 specific.
4. General clean up of the MBlaze backend code. Much of the
tablegen code has been cleanup and simplified.
Bug Fixes:
1. Removed duplicate periods from subtarget feature descriptions.
2. Many of the instructions had bad machine code information
in the tablegen files. Much of this has been fixed.

The MicroBlaze backend was generating stack layouts that did not
conform correctly to the ABI. This update generates stack layouts
which are closer to what GCC does.
Variable arguments support was added as well but the stack layout
for varargs has not been finalized.
