Hot/cold partitioning update patch. The problems that this patch
attemptd to address/fix are:
- Fix places where adding in_unlikely_executed_text to the enum data
type "in_section" threw off switch case statements.
- Make it work correctly (by turning it off) for functions where user
specifies "__attribute__ section"
- Make it work correctly (by turning it off) for linkonce sections
- Make it work correctly with -ffunction-sections flag
- Make it output correct cold section labels
- Undo some changes to original assembly code generation
- Turn off hot/cold partitioning in the presence of DWARF debugging (for
the moment)
- Turn off hot/cold partitioning for architectures that do not support
named sections
- Use variables rather than constants for cold section labels and names (to
work correctly with -ffunction-sections, among other things)

condition that fallthru edges are not allowed to cross section
boundaries.
* defaults.h (NORMAL_TEXT_SECTION_NAME): Remove this.
