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.

[r27115]

[r27114]

[r27113]

[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.
