708e7c29bc Remove RequireDefault parameter from EmitCaseConstructHandler.
There are now no situations when 'default' is required.

For instance, the following command:

    llvmc2 -E hello.c

08bd2e74dc Add support for user-provided hooks and environment variable reads to the cmd_line tool property.
Used like this: (cmd_line "$CALL(MyHook) --option -o $ENV(VARIABLE) $CALL(AnotherHook)")
Also works with case expressions.

Hook declarations are auto-generated, the definitions should be provided by the user
(just drop a .cpp file in the tools/llvmc2 directory).

Hooks should live in the "hooks" namespace and have type std::string hooks::Hook(void).

b4106170dd Add patterns for CALL32m and CALL64m. They aren't matched in most
cases due to an isel deficiency already noted in
lib/Target/X86/README.txt, but they can be matched in this fold-call.ll
testcase, for example.

This is interesting mainly because it exposes a tricky tblgen bug;
tblgen was incorrectly computing the starting index for variable_ops
in the case of a complex pattern.

d35121ad00 Fix a tblgen problem handling variable_ops in tblgen instruction
definitions. This adds a new construct, "discard", for indicating
that a named node in the input matching pattern is to be discarded,
instead of corresponding to a node in the output pattern. This
allows tblgen to know where the arguments for the varaible_ops are
supposed to begin.

This fixes "rdar://5791600", whatever that is ;-).

8370d38ade Add a flag to indicate that an instruction is as cheap (or cheaper) than a move
instruction to execute. This can be used for transformations (like two-address
conversion) to remat an instruction instead of generating a "move"
instruction. The idea is to decrease the live ranges and register pressure and
all that jazz.

6422e8aa1c Do not generate by TableGen the hard-coded standard, target-independent part of
DAG instruction selectors. Introudce a dedicated header file for this part:
include/llvm/CodeGen/DAGISelHeader.h

TableGen now only generates the include preprocessor directive to include this
new header.

This is a preparation for supporting multiple implementations of instruction
selectors in the future.

ee4fa1977d Move instruction flag inference out of InstrInfoEmitter and into
CodeGenDAGPatterns, where it can be used in other tablegen backends.
This allows the inference to be done for DAGISelEmitter so that it
gets accurate mayLoad/mayStore/isSimpleLoad flags. 

This brings MemOperand functionality back to where it was before
48329. However, it doesn't solve the problem of anonymous patterns
which expand to code that does loads or stores.
