<pre>Currently, LLD leaves padding between executable sections as-is, so they are 0.
That is not desirable for a few reasons.
1. Disassemblers would interpret the sequences of 0 bytes at end of each
function as machine instructions and print out bogus disassembly.
2. Leaving executable 0 bytes could potentially make some attack easier.
We want to fill gaps with trap instructions. On x86 and x86-64, that is 0xcc,
for example.</pre>
