Use movaps / movapd (instead of movss / movsd) to do FR32 / FR64 reg to reg
transfer.
According to the Intel P4 Optimization Manual:
Moves that write a portion of a register can introduce unwanted
dependences. The movsd reg, reg instruction writes only the bottom
64 bits of a register, not to all 128 bits. This introduces a dependence on
the preceding instruction that produces the upper 64 bits (even if those
bits are not longer wanted). The dependence inhibits register renaming,
and thereby reduces parallelism.
Not to mention movaps is shorter than movss.

If we have zero initialized data with external linkage, use .zerofill to
emit it (instead of .space), saving a bit of space in the .o file.
For example:
int foo[100];
int bar[100] = {};
when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space. The X86 backend can also do this on darwin.
