Prior to this PR, `int`, `signed int`, and `unsigned int`
bitfields are all treated as `unsigned int`.
With this PR, `signed int` will be treated as `signed int`,
and the others remain unsigned.
Since `Type` does not distinguish between `int` and `signed int`,
add an extra `int* SignenessSpecified` param to `ParseTypeSpec`
so we can tell these apart for bit-fields and treat plain `int : N`
as `unsigned int : N` since it is more efficient to zero-extend
than sign-extend.
Fixes#1095
Renamed GetReplacementType() to GetStructReplacementType().
Clarified in comments that most *Struct* facilities work for unions as well.
Made it clear in some error messages with regards to structs/unions.
possible to use the opposite type with the tag name. That is "struct a" after
declaring "union a" and vice versa.

situations (extern symbols without attached import, because the import wasn't
referenced and therefore removed by the assembler).

elements to a string of structs, each representing one type element. This
should fix problems on unusual architectures, since it is no longer necessary
to embedd pointers and other data converted to numbers in the string of
unsigned shorts.
Increased the TypeCode length to unsigned long to make room for more type
bits.
Inline more functions in datatype.h.

Changed/added several optimizer steps to detect register variables correctly
or to handle them in a special way.

Several renames for better readibility.
Removed separate struct and enum symbol tables in favour of one tag table.
Check for some more error conditions or dubious constructs.
