3f8b8913bc Autogenerate code to map from GCC builtin to LLVM intrinsic.

09a053a777 Allow a sequence of digits at the end of the directory name when trying to 
determine the top directory. This allows the tool to find the correct top
directory when you have something like:

   /x/llvm
   /x/llvm2
   /x/llvm3

Previously the scripts would always find /x/llvm even if you were in the
llvm2 or llvm3 directory because the pattern didn't allow the digits at
the end of the path.

it possible when a TokenFactor is between the load and store. But is still
missing some cases due to ordering issue.

6f8aaf2cb0 Don't generate silly matching code like this: 
if (N1.getOpcode() == ISD::ADD &&
     ...)
   if (... &&
       (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) &&
       ...)

TableGen knows N1 must have more than one operand.

04cadb3684 Add support for modifier strings in machine instr descriptions. This allows 
us to avoid creating lots of "Operand" types with different printers, instead
we can fold several together and use modifiers.  For example, we can now use:

${target:call} to say that the operand should be printed like a 'call' operand.

e41bf82107 Allow more loads to be folded which were previously prevented from happening 
due to ordering issue. i.e. they were selected for chain use first.
Now at load select time, check if it is being selected for a chain use and if
it has only a single real use. If so, return a HANDLENODE (with the load as
its operand) in its place and record it.
When it is folded or the load is selected for a real use, the isel records it
as the replacement for the HANDLENODE. The replacement is done when all nodes
are selected.
This scheme exposed a couple of problems where cycles can happen. (See comments
in EmitMatchCode() for descriptions of the problems and their workaround /
solutions.) These problems have been resolved with a small compile time
penality.

e4a8a6e645 (store (op (load ...))) folding problem. In the generated matching code, 
Chain is initially set to the chain operand of store node, when it reaches
load, if it matches the load then Chain is set to the chain operand of the
load.

However, if the matching code that follows this fails, isel moves on to the
next pattern but it does not restore Chain to the chain operand of the store.
So when it tries to match the next store / op / load pattern it would fail on
the Chain == load.getOperand(0) test.

The solution is for each chain operand to get a unique name. e.g. Chain10.

67a202bc42 now that we have control over emission of the code, emit the code using nested 
"if" statements (indenting it appropriately, of course) instead of using goto's.

This inverts the logic for all of the if statements, which makes things simpler
to understand in addition to making the generated code easier to read.

8a0604b523 Change PatternCodeEmitter to emit code into a buffer instead of emitting it 
directly to the output file.  This makes things simple because the code doesn't
have to worry about indentation or the case when there is no goto.  It also
allows us to indent the code better without touching everything :)

If store's chain operand is load, then use load's chain operand instead. If
it isn't (likely a TokenFactor), then do not allow the folding.

1feeeecf4c Another folding problem: if a node r/w chain or flag, don't fold it if it 
has already been selected. The number of use check is not strong enough since
a node can be replaced with newly created target node. e.g. If the original
node has two uses, when it is selected for one of the uses it is replaced with
another. Each node now has a single use but isel still should not fold it.

76356d9594 Prevent folding of a node with multiple uses if the node already folds a load! 
Here is an example where the load ended up being done twice:

%A = global uint 0

uint %test(uint %B, ubyte %C) {
	%tmp = load uint *%A;
	%X = shl uint %tmp, ubyte %C
	%Cv = sub ubyte 32, %C
	%Y = shr uint %B, ubyte %Cv
	%Z = or uint %Y, %X
	store uint %Z, uint* %A
	ret uint %Z
}

==>

	subl $4, %esp
	movl %ebx, (%esp)
	movl 8(%esp), %edx
	movl A, %eax
	movb 12(%esp), %bl
	movb %bl, %cl
	shldl %cl, %edx, %eax
	movb %bl, %cl
	shldl %cl, %edx, A
	movl (%esp), %ebx
	addl $4, %esp
	ret

7419de89fb Use pattern information to determine whether the use expects this 
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.
