[llvm] Remove unneeded cl::ZeroOrMore for cl::opt options. NFC
Some cl::ZeroOrMore were added to avoid the `may only occur zero or one times!`
error. More were added due to cargo cult. Since the error has been removed,
cl::ZeroOrMore is unneeded.
Also remove cl::init(false) while touching the lines.

This reverts commit e64afefdf88d2607c476f13de05193c0f8991976. It caused

[PGO][PGSO] Handle MBFIWrapper
Some code gen passes use MBFIWrapper to keep track of the frequency of new
blocks. This was not taken into account and could lead to incorrect frequencies
as MBFI silently returns zero frequency for unknown/new blocks.
Add a variant for MBFIWrapper in the PGSO query interface.
