Added assertion that Block-level statements should not be NULL.

- Added ability to emit cross class register copies to the BBRU scheduler.
- More aggressive backtracking.

- Added MRegisterInfo::getCrossCopyRegClass() hook. For register classes where reg to reg copies are not possible, this returns another register class which registers in the specified register class can be copied to (and copy back from).
- X86 copyRegToReg() now supports copying between EFLAGS and GR32 / GR64 registers.

Some assemblers do not recognize aliases pushfd, pushfq, popfd, and popfq. Just emit them as pushf and popf.

BUG 1) 

CFG failed to build for empty functions, or functions containing only
NullStmts or empty compound statements.

We now handle such cases, although now we cannot test for CFG
construction failure by asserting that the last block constructed is
not NULL (since it now may be).

BUG 2)

CFG construction segfaulted on some cases when walking the AST and not
taking into account that some children of a statement may be NULL.

Also eliminated allocas from the Ocaml bindings for portability,
and avoided unnecessary casts.

using "-parse-ast -verify".

Updated all test cases (using a sed script) that invoked -parse-ast-check to
now use -parse-ast -verify.

Fixed a bug where using "-verify" instead of "-parse-ast-check" would not
correctly create the DiagClient needed to accumulate diagnostics.

ASTConsumer can also be verified using the diagnostics checker.  From
the command line, users may activate diagnostic checking using the
"-verify" option.  For example, "clang -verify -warn-dead-stores"
checks if the warnings flagged by the dead store checker match those
in the comments.

Note that we still have the option "-parse-ast-check" for backwards
comptability with existing test cases.  This option is now equivalent to 
"-parse-ast -verify".
