fd530e8c6a Add a check for side effect-free options (specified only in the OptionList).

3cc06cc83a 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.

85844e2353 Make it possible to test if the '-o' option is provided. 
The following is now allowed:

    (case (not_empty "o"), do_something, ...)

This didn't work previously because "-o" is built-in.

9c0a984b65 Allow nesting of case expressions. 
The following is now legal:

    (case (in_language "c"),
          (case (switch_on "E"), "gcc -x c -E $INFILE", (default), "gcc -x c $INFILE"),
          (default),
          "gcc $INFILE $OUTFILE")

c9f69ac2fe Make it possible to change the output file suffix based on command-line options. 
For instance, the following command:

    llvmc2 -E hello.c

now generates a file with the correct suffix (hello.i).

7ded98d7b6 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).

aa8fcd5657 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.

4e87d82476 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 ;-).

b56bc61cf4 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.

7e3ffb268e 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.
