Disable HPR support at the option level in preparation for the
codebase-wide removal of the feature. Disabling support early fixes
several HPR related issues which have been propping up over the last
few months since some initial refactoring was checked in which enabled
fatal assertions which are now catching pre-existing HPR bugs which
have been lurking in the codebase causing runtime issues.
As a tactical fix, disabling HPRs will "fix" all of these problems. A
subsequent PR will perform the codebase-wide cleanup which will enable
us to greatly simplify and make sense of the register allocator on Z.
