[PATCH] testsuite: Add new effective target keywords

[Björn Haase <bjoern dot m dot haase at web dot de>]

Hi,

when preparing to prepare the testsuite to be better adapted also for small 
targets, I have made use of the approach that you had suggested. You will 
find attached a patch that defines three new effective-target keywords:

nested_functions
trampolines
int_larger_than_16_bits

All of those make use of the knowledge stored in the board information 
variables. With the new keyword "trampolines" it now will also be possible to 
uprightly skip tests that use trampolines instead of continuing to report the 
testcases to pass. Difference to the previous patch is, that now explicit 
functions are used for implementing the new keywords.

The attached patch also adds "avr-*-*" to the list of targets that do not 
support profiling.

Yours,

Björn

        * lib/target-supports.exp: Add effective-target keywords 
"nested_functions",
          "trampolines" and "int_larger_than_16_bits". Add "avr-*-*" to the 
list of
          targets without support for profiling.
