S/390: Remove loc splitter · 561f6312

The backend splitter splitting a 3 operand load on condition into 2 is
wrong.  The S/390 load on condition instruction might trap on the
memory operand even if the condition is false.  So if the first load
on condition overwrites a register used as part of the memory address
of the second the second might trigger a segfault even if it does not
actually perform the load.

Trying to fix this I noticed that the generated code looks anyway
better without the splitter.  So removing the splitter entirely is the
way to go here.

[arm] Fix warning in parsecpu.awk · 1ff62510

    
In awk, single quotes within a quoted string do not need escaping.
The existing code causes awk to grumble in the build logs.
    
	* config/arm/parsecpu.awk (gen_comm_data): Do not escape single quotes
	in quoted strings.

(really commit it this time)...
