rs6000: Consolidate target built-ins code
Continuing with the refactoring effort, this patch moves as much of the
target-specific built-in support code into a new file, rs6000-builtin.cc.
However, we can't easily move the overloading support code out of
rs6000-c.cc, because the build machinery understands that as a special file
to be included with the C and C++ front ends.
This patch is just a straightforward move, with one exception. I found
that the builtin_mode_to_type[] array is no longer used, so I also removed
all code having to do with it.
The code in rs6000-builtin.cc is organized in related sections:
- General support functions
- Initialization support
- GIMPLE folding support
- Expansion support
Overloading support remains in rs6000-c.cc.
