Benjamin Kramer 1118860e3a simplify-libcalls: fold strstr(a, b) == a -> strncmp(a, b, strlen(b)) == 0

Nick Lewycky aee2632be3 The memcpy intrinsic only takes i8* for %src and %dst, so cast them to that
first. Fixes PR7265.

Eric Christopher 7258dcd77f Revert 101465, it broke internal OpenGL testing.
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

Gabor Greif f375520f7b reapply r101434
with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

Eric Christopher 1f272f7fd8 Verify function prototypes before trying to optimize functions. We also
need TargetData, just return false if we don't have it.

Update testcases accordingly.

Fixes PR6807.

Mon P Wang c576ee9040 Reapply address space patch after fixing an issue in MemCopyOptimizer.
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

Eric Christopher 87abfc506f Move SimplifyLibCalls's LibCall builders to a separate file so they
can be used in more places.  Add an argument for the TargetData that
most of them need. Update for the getInt8PtrTy() change.  Should be
no functionality change.
