37cdad3e59 Fix the position of MemOperands in nodes that use variadic_ops
in DAGISelEmitter output. This bug was recently uncovered by the
addition of patterns for CALL32m and CALL64m, which are nodes
that now have both MemOperands and variadic_ops.

This bug was especially visible with PIC in various configurations,
because the new patterns are matching the indirect call code used
in many PIC configurations.

e4c67cdab4 Teach the DAGISelEmitter to not compute the variable_ops operand
index for the input pattern in terms of the output pattern. Instead
keep track of how many fixed operands the input pattern actually
has, and have the input matching code pass the output-emitting
function that index value. This simplifies the code, disentangles
variables_ops from the support for predication operations, and
makes variable_ops more robust.

e43228958c New feature: OptionList.
It can be handy to have all information about options gathered in a single place
to provide an overview of all supported options. This patch allows the following:

def Options : OptionList<[
(switch_option "E", (help "Help string")),
(alias_option "quiet", "q")
...
]>;

Tool-specific option properties (like 'append_cmd') have (obviously) no meaning in
this context, so the only properties that are allowed are 'help' and 'required'.

See usage example in examples/Clang.td.

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.
