Added field noResults to Instruction.
...
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

This ugly patch works around a GCC bug where it is compiling SelectCode to
...
use too much stack space, overflowing the stack for large functions. Instead
of emitting new SDOperands in each match block, we emit some common ones at
the top of SelectCode then reuse them when possible.
This reduces the stack size of SelectCode from 28K to 21K. Note that GCC
compiles it to 512 bytes :-/
I've filed GCC PR 25505 to track this.

At top of generated isel SelectCode() is this:

if (!N.Val->hasOneUse()) {
std::map<SDOperand, SDOperand>::iterator CGMI = CodeGenMap.find(N);
if (CGMI != CodeGenMap.end()) return CGMI->second;
}
Suppose a DAG like this:
X
^ ^
/ \
USE1 USE2
Suppose USE1 is being selected first and during which X is selected and
returned a new node. After this, USE1 is no longer an use of X. During USE2
selection, X will be selected again since it has only one use!
The fix is to always query CodeGenMap.

type constraint. This lets tblgen realize that it doesn't need any dynamic

Implement a couple of new (important) features.
...
1. If an operation has to be int or fp and the target only supports one
int or fp type, relize that the op has to have that type.
2. If a target has operations on multiple types, do not emit matching code
for patterns involving those operators, since we do not emit the code to
check for them yet. This prevents PPC from generating FP ops currently.
Also move some code around into more logical places.

Currently we check that immediate values live on the RHS of commutative
operators. Defining ORI like this, for example:
def ORI : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2),
"ori $dst, $src1, $src2",
[(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;
results in:
tblgen: In ORI: Instruction can never match: Immediate values must be on the RHS of commutative operators!
