pointer and length, and allocate the arrays in ScalarEvolution's
BumpPtrAllocator, so that they get released when their owning
SCEV gets released. SCEVs are immutable, so they don't need to worry
about operand array resizing. This fixes a memory leak reported
in PR6637.

instructions to help disassembly.

We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

And modified test cases to not expect '+' in +reg or #+num.  For example,

; CHECK:       ldr.w	r9, [r7, #28]

Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*.

libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

This is for the disassembly work.

There are cases where this is not possible, for example, A8.6.53 LDM Encoding T1.
In such case, we'll use an adhoc approach to deduce the Opcode programmatically.
