powerpc: Fix location and rename exception trampolines
The symbols that name some of our exception trampolines are ahead of the
location they name. In most cases this is OK because the code is tightly
packed, but in some cases it means the symbol floats ahead of the
correct location, eg:
c000000000000ea0 <performance_monitor_pSeries_1>:
...
c000000000000f00: 7d b2 43 a6 mtsprg 2,r13
Fix them all by moving the symbol after the set of the location.
While we're moving them anyway, rename them to loose the camelcase and
to make it clear that they are trampolines.
