target-sparc: Store %asi in TB flags
Knowing the value of %asi at translation time means that we can handle the common settings without a function call. The steady state appears to be %asi == ASI_P, so that sparcv9 code can use offset forms of lda/sta. The %asi register gets pushed and popped on entry to certain functions, but it rarely takes on values other than ASI_P or ASI_AIUP. Therefore we're unlikely to be expanding the set of TBs created.
