[llvm] [opt] Improve help message (PR #97805)

[Nabeel Omer via llvm-commits]

https://github.com/omern1 created https://github.com/llvm/llvm-project/pull/97805

This patch changes all single quotes in the help text to double quotes for the sake of cross platform correctness.

The single quotes previously used in the help message are correct for bash and most other shells but aren't correct for the Windows command prompt as it only interprets double quotes in the manner intended in the help message.

This patch was prompted by the fact that if you aren't aware of the aformentioned quirk the single quotes result in very confusing error messages from the command prompt.

Subject: [PATCH] [opt] Improve help message

This patch changes all single quotes in the help text to
double quotes for the sake of cross platform correctness.

The single quotes previously used in the help message are correct for
bash and most other shells but aren't correct for the Windows command
prompt as it only interprets double quotes in the manner intended in the
help message.

This patch was prompted by the fact that if you aren't
aware of the aformentioned quirk the single quotes result in very
confusing error messages from the command prompt.
