I have about 12,500 tracks uploaded to iTunes Match. From my desktop and laptop, everything works great. I can see the cloud-based tracks and play them. I can download them to my machines.
When I turn on iTunes Match and select "Show All Music" on my iPhone the Music app shows me nothing at all. Specifically, it shows me this:
I've tried leaving it plugged in, with the Music app open, over night to see if the progress bar fills in a bit and it never does. Not even a little bit.
If I turn off the "Show All Music" option, the Music app shows the tracks I had sync'ed to the device before I signed up for iTunes Match and put all my tracks in the cloud.
How can I get my entire iTunes Match-based music library to appear on my iPhone?

There could be a corruption in your music library that is preventing the 'sync' to finish.
If the issue is still persists, try deleting your Music library using iExplorer
If the issue still persists I would recommend you do a complete restore through iTunes
