OPR_LOCAL with OPR_REFERENCE operands can be supported later.

This is compatible with TP7's inline asm, and perhaps also with tasm/masm/delphi.

record field). This makes e.g.
test [di + recordtype], 1
work and use the size of recordtype to determine the operand size; recordtype
itself is evaluated to 0, so if recordtype's size is 2 bytes, the above
instruction assembles as:
test word ptr [di], 1
Ugly, but TP7 compatible.

which allows const symbol expressions to also have a size sometimes. Why?
Because TP7 (and perhaps Delphi) allows not specifying the size in e.g.
test [di+recordtype.recordfield], 1
in this case, the operand size (byte ptr, word ptr, dword ptr, qword ptr) is
determined by the size of recordtype.recordfield; this already happens with
variables, but in this case, this is a type.field, which is resolved to a
constant.
This commit only adds a dummy 'size' parameter, which is always initialized to
0 and not used. The actual implementation of the above will follow in separate
commits.

tx86intreader.BuildConstSymbolExpression; it returns whether the 'OFFSET'
keyword has been used in the expression. This will be used for disambiguation
between 'dd xx' and 'dd offset xx', because they should produce different
results on i8086 (the first generates a far pointer, i.e. the same as
'dw xx, SEG xx', the second - a 32-bit offset)

the intel assembler reader: no longer parse them as register tokens,
but as local operands that are later converted into registers. This
ensures in particular that the type of the operand is set, which is
necessary in case this operand later subscripted (as in tasm10a)
