RFR(M): 8204240: Extend MDO to allow more reasons to be recorded per bci

[Doerr, Martin]

Hi Roland,

we just noticed that this change causes a build warning on Windows 32 bit:
jdk\src\hotspot\share\oops/methodData.hpp(142) : warning C4293: '<<' : shift count negative or too big, undefined behavior

I think trap_mask is incorrect for 32 bit and should get fixed.

Best regards,
Martin
