Moved LoadExpr + support functions into a separate module.
Removed obsolete files.
Some cleanup and makefile adjustments.

Improved the inlining of standard C functions. Added more standard functions
to inline.

ExprDesc structure, not as separate value.
WARNING: The current code does compile but does not work correctly, because
the lvalue flag is part of ExprDesc.Flags and not masked out in several tests
throughout the code.

argument to the sizeof operator, if the type spec is starting with this
keyword.

The Test() and TestInParens() functions do now return information about the
expression that was tested.
An if... statement where the expression is always true will now print a
warning "Unreachable code" if it has an else clause.

correctly if it did not contain an explicit comparison operator.
Removed an old hack from the test subroutine that did no longer work.

When assigning structures, copy them using the primary register when the
size is 1, 2, or 4.
When assigning structures, allow structures by value when the size is 1,
2, or 4. These structures are expected to be in the primary register. The
only case when this can happen is by return from function, so this change
makes div() work.

Allow the second and third operand of the :? operator to be of type int.

Fixed a problem with K&R functions: In a function with no return type
specified, the compiler did not allow a simple "return" statement. However,
there was no "void" type at that time, so it was not possible to specify
something else. The solution is to allow omission of a return value in a
K&R function with an implicit int type. Other types or an explicit int is
still checked.

cdecl functions, this generates better code.
Remove a small error that caused indirect non fastcall function to always be
handled as variadic, which meant a useless load of the Y register was added.
