ARM: cppInterpreter_arm.S: Designate function labels as such; required for thumb interworking.

[Xerxes Rånby]

Thanks to aph and Ringding we have today tracked down one obscure bug that prevented the ARM assembler interpreter and Thumb2 JIT to work on some ARM systems.
http://icedtea.classpath.org/hg/icedtea6/rev/f7f8d71c851c37ee9ff1ee1f13e7e899d3cf90c0

What was happening was that the gcc linker did not have enough information to figure out when to convert a bl function calls to blx for proper thumb inter-working.
By adding the .type globalname, %function to all .global 's provided the linker with enough information to generate correct
arm -> thumb and thumb -> arm function calls.

Cheers
