* Types for pop stack/push stack
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* 1 I1/U1
* 2 I2/U2
* 4 I4/U4
* 8 I8/U8
* r R4
* d R8
* o objref (can be an array or null)
* [ single dimensional array of (prefix)
* & byref/managed ptr (prefix)
*
* Pop only
* ~~~~~~~~
* R real number
* N number -any integer or real number
* Q number or unmanaged pointer
* X number, unmanaged pointer, managed pointer, or objref [Obsolete]
* Y integer (I1..I4), unmanaged pointer, managed pointer, or objref
* I Integral type (1, 2, 4, or 8 byte, or platform-independent integer type)
* A Anything
*
* CE "ceq" semantics - pop 2 arguments, do type checking as if for "ceq" instruction:
* Integer Real ManagedPtr UnmanagedPtr Objref
* Integer y
* Real y
* ManagedPtr y y
* UnmanagedPtr y
* Objref y y
*
* CG "cgt" semantics - pop 2 arguments, do type checking as if for "cgt" instruction:
* Integer Real ManagedPtr UnmanagedPtr Objref
* Integer y
* Real y
* ManagedPtr y
* UnmanagedPtr
* Objref y
*
* = Pop another item off the stack, and it must be the same type (int,real,objref,etc.) as the
* last item popped (note, System.Int32 <-> I4 etc. are allowed). Other value
* classes are NOT allowed.
*
* i (deprecated) Platform independent size value, but NOT an objref (I4/R4/ptr on 32-bit, I8/R8/ptr on 64-bit)
* p (deprecated) Platform independent size value OR objref
* * (deprecated) anything
* Push only
* ~~~~~~~~~
* n null objref (valid for push only)
* - Rewind the stack to undo the last pop (you cannot have trashed that location, though)
*
* Usage: <pop stack> : <operand checks> <push stack> <branches> <!>
*
* Order is important! Operand checks come after pop stack and before push stack.
* For example, to check the operand being a valid local variable number (only), do ":L"
*
* If there is a "!" at the end, it means the instruction is either invalid, not supported, or that
* there is a case statement to handle the instruction. If no case statement exists, the verifier
* will fail verification of the method.
*
* ! can be used to perform some operand checks and/or stack pops/pushes, while still allowing specific
* behavior; e.g. verifying that the inline operand is a valid local variable number.
*
* <operand checks>
* ~~~~~~~~~~~~~~~~
* #d Overwrite inline operand with digit "d" (must be in 0...9 range)
* L Check that the operand is a valid local variable number.
* A Check that the operand is a valid argument number.
*
* <branches>
* ~~~~~~~~~~
* b1 - one byte conditional branch
* b4 - four byte conditional branch
* u1 - one byte unconditional branch
* u4 - four byte unconditional branch
* l1 - one byte leave
* l4 - one byte leave
*
