78e3e521cd Arrange to print constants that match "n" and "i" constraints
in inline asm as signed (what gcc does).  Add partial support
for x86-specific "e" and "Z" constraints, with appropriate
signedness for printing.

1823c92aa7 fix the X86 backend to just drop llvm.declare nodes for VLAs instead of
leaving them in the DAG and then getting selection errors.  This is a 
fix for PR3538.

cc994ea36b Delete the heuristic for non-livein CopyFromReg nodes. Non-liveinness
is determined by whether the node has a Flag operand. However, if the
node does have a Flag operand, it will be glued to its register's
def, so the heuristic would end up spuriously applying to whatever
node is the def.

85b0edec46 Make a transformation added in 63266 a bit less aggressive.
It was transforming (x&y)==y to (x&y)!=0 in the case where
y is variable and known to have at most one bit set (e.g. z&1).
This is not correct; the expressions are not equivalent when y==0.
I believe this patch salvages what can be salvaged, including
all the cases in bt.ll.  Dan, please review.
Fixes gcc.c-torture/execute/20040709-[12].c

752272a5e5 Implement PR3495: local spiller optimization. The local spiller can now keep availability information over BB boundaries. It visits BB's in depth first order. After visiting a BB if it find a successor which has a single predecessor it visits the successor next without clearing the availability information. This allows the successor to omit reloads or change them into copies.

doesn't have to worry about this additional information.

7dfa07f794 Don't print extra spaces in vector and array constants. This makes
them visually more consistent with vector and array types.

5cffa6fe27 Use iterators to iterate through the Preds array instead of
an index. This code is on the hot-path because the current
