7a40eaacee Do a separate pass to compute spill weights because doing it inline
with live intervals was missing registers that were used before they
were defined (in the arbitrary order live intervals numbers
instructions).

1715ce00e4 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.

1118d0fd94 Fix PR#193.
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.

e0bb3e766d 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.
