Instead of storing operands as std::vector<Use>, just maintain a pointer
...
and num operands in the User class. this allows us to embed the operands
directly in the subclasses if possible. For example, for binary operators
we store the two operands in the derived class.
The has several effects:
1. it improves locality because the operands and instruction are together
2. it makes accesses to operands faster (one less load) if you access them
through the derived class pointer. For example this:
Value *GetBinaryOperatorOp(BinaryOperator *I, int i) {
return I->getOperand(i);
}
Was compiled to:
_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
movl 4(%esp), %edx
movl 8(%esp), %eax
sall $4, %eax
movl 24(%edx), %ecx
addl %ecx, %eax
movl (%eax), %eax
ret
and is now compiled to:
_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
movl 8(%esp), %eax
movl 4(%esp), %edx
sall $4, %eax
addl %edx, %eax
movl 44(%eax), %eax
ret
Accesses through "Instruction*" are unmodified.
3. This reduces memory consumption (by about 3%) by eliminating 1 word of
vector overhead and a malloc header on a seperate object.
4. This speeds up gccas about 10% (both debug and release builds) on
large things (such as 176.gcc). For example, it takes a debug build
from 172.9 -> 155.6s and a release gccas from 67.7 -> 61.8s

This giant patch speeds up Type::isSized(). Before, this would have to search
...
large nested types over and over again to determine if they are sized or not.
Now, isSized() is able to make snap decisions about all concrete types, which
are a common occurance (and includes all primitives).
On 177.mesa, this speeds up DSE from 39.5s -> 21.3s and GCSE from
13.2s -> 11.3s, reducing gccas time from 80s -> 61s (this is a debug build).
DSE and GCSE are still too slow on this testcase, but this is a simple
improvement.

Add a hook to find out how the target handles shift amounts that are out of
