Modified the linker so that it always links in an object from an archive
...
that defines the symbol "main." This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.
There is probably a more correct way to do this, but this works for now.

Modified ReadArchiveBuffer() so that it dynamically allocates the
std::string object used to hold the bytecode object file's name. This is
necessary because it is passed by reference to the new Module that is
allocated to represent the bytecode object, and previously we were
using a std::string that disappeared on function exit.

Remove floating point killer pass. This is now implemented in the

instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.
