Fix a long-standing wart in the code generator: two-address instruction lowering
...
actually *removes* one of the operands, instead of just assigning both operands
the same register. This make reasoning about instructions unnecessarily complex,

up operand #'s with the target description file.
Changing this also gets rid of a bunch of hacky code in various places.
This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.

Completely rearchitect the interface between targets and the pass manager.
...
This pass:
1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
output, move all this to common code, and give targets hooks they can
implement.
3. Commonalize the target population stuff between file emission and JIT
emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
paves the way for "fast -O0" stuff in the CFE later, and now LLC could
lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
which is now orthogonal to the fact that JIT'ing is being done.

Make the ProgramName variable a std::string so we can eliminate the path
...
portion fo the program name via sys::Path().getLast(). This makes error
messages more readable since this is invariably used only in error
messages. Instead of:
/path/to/llvm/bin/directory/toolname: error message
we will now get:
toolname: error message
Also, since we always have a program name (even if its defaulted), don't
check to see if it is set or not when generating error messages. This
eliminates a bunch of constant strings, saving a little under 1K of data.

Adjust users of MappedFile to its new non-throwing interface. Note that in
most cases the lazy step of just throwing after a call to MappedFile was
installed. This was done in the name of incremental changes. Getting rid of
the new throw statements will take adjustment of interfaces and propagation
of errors to higher levels. Those changes will come in subsequent patches.

1. Actually turn on -fno-exceptions in libraries that do not have the
REQUIRES_EH option in their Makefile. The following library file size
savings were made (DEBUG):
libLLVMDataStructure.a 525K
libLLVMCore.a 380K
libLLVMCodeGen.a 350K
libLLVMTransformUtils.a 305K
libLLVMScalarOpts.a 270K
libLLVMAnalysis.a 247K
libLLVMSelectionDAG.a 233K
libLLVMipo.a 175K
LLVMX86.o 123K
LLVMPPC.o 81K
libLLVMipa.a 17K
TOTAL 2,706K
Note that the savings is actually a little larger than this because
I didn't count any of the libraries that had small changes.
2. Remove REQUIRES_EH from the AsmParser library as it is now exception
free. This resulted in a nearly 78K drop in the size of the debug
library for AsmParser.

Rid the Assembly Parser of exceptions. This is a really gross hack but it
will do until the Assembly Parser is re-written as a recursive descent.
The basic premise is that wherever the old "ThrowException" function was
called (new name: GenerateError) we set a flag (TriggerError). Every
production checks that flag and calls YYERROR if it is set. Additionally,
each call to ThrowException in the grammar is replaced with GEN_ERROR
which calls GenerateError and then YYERROR immediately. This prevents
the remaining production from continuing after an error condition.
