  Log Message:
  -----------
  [CodeGen] Do not split functions with attr "implicit-section-name".

The #pragma clang section can be used at a coarse granularity to specify
the section used for bss/data/text/rodata for global objects. When split
functions is enabled, the function may be split into two parts violating
user expectations.
