implement several new section types including comdat for ELF, this potentially breaks COFF and MACHO (will fix it asap)

Kicked useless memory allocation and casts.

[r27120]

C99 feature removed.

[r27119]

[r27118]

Moved comments AFTER the ifs (where they belong to).

[r27117]

[r27116]

do not free the graph after emitting it (this should only change the peak memory allocation of firm marginally). The gas dumper needs the irg info sometimes.

[r27110]

support for local common symbols (whatever that is good for); introduce ir_visibility_private (not tested yet as they don't occur in C)

[r27109]

put zero initialized entities into bss section (not just uninitialized ones); TLS entities should go to tbss or tdata

This uses the vrp information to evaluate int projs.
This optimizes cases like:
x |= 33;
y = x & 96;
to y = 1;

[r27100]

This uses the vrp information to expand the handling for constants to
handling ranges as well.

[r27098]

This adds some basic optimizations, e.g. to calculate the value for some
nodes if it can be determined.

[r27097]

This commit adds the basic analysis needed to derive vrp information. It
should not run infinetely, but there may be border cases.
There might be error conditions for which there are no checks yet.
Also, a lot of the derivations can still be improved.

[r27096]

This commit adds the code and prototypes for dumping vrp information

[r27095]

This commit adds the neccessary attributes to each ir_node. It also adds
the initialization code and some prototypes for the graph_pass and some
support functions.
