Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

Calling save_expr produces something that is evaluated and recorded
the first time expand_expr is called on it. Subsequent calls to
expand_expr just reuse the recorded value.
The call to expand_expr that generates code that actually computes
the value is the first call *at compile time*. Subsequent calls
*at compile time* generate code to use the saved value.
This produces correct result provided that *at run time* control
always flows through the insns made by the first expand_expr

You, the caller of save_expr, must make sure this is so.
