include/nuttx: Map the GCC asm keyword spellings for the TASKING compiler.
The TASKING VX-toolset accepts __asm, asm and the __asm volatile
sequence, but neither __asm__ nor __volatile__ nor the asm volatile
sequence. The sources that use the GCC spellings, e.g. the tricore
hwdebug support, therefore fail to compile with a syntax error.
Redirect the double underscore spellings to __asm and plain volatile
in the TASKING branch of compiler.h. The GNU and LLVM builds are
unaffected: the block is guarded by __TASKING__.
