    Test on solib load and unload
    This patch is to add a test case to on the performance of GDB handling
    load and unload of shared library.
    In V4:
     - Handle malloc and dlopen failure,
     - Document test parameters.
    In V3, there are some changes,
     - Adapt to perf test framework changes.
     - Measure load and unload separately.
    In V2, there are some changes,
     - A new proc gdb_produce_source to produce source files.  I tried to
       move all source file generation code out of solib.exp, but
       compilation step still needs to know the generated file names.  I
       have to hard-code the file names in compilation step, which is not
       good to me, so I give up on this moving.
     - New variable SOLIB_DLCLOSE_REVERSED_ORDER to control the order of
       iterating a list of shared libs to dlclose them.
     - New variable GDB_PERFORMANCE to enable these perf test cases.
     - Remove dlsym call in solib.c.
     - Update for the updated framework.
    	* lib/gdb.exp (gdb_produce_source): New procedure.
    	* gdb.perf/solib.c: New.
    	* gdb.perf/solib.exp: New.
    	* gdb.perf/ New.;h=71c0c615953a33316f5372ad297a92f341d40ba9

    Perf test framework
    This patch adds a basic framework to do performance testing for GDB. is about the test case, is about test
    results, and how are they saved. is about how results
    are reported (in what format). is about measuring the
    execution of tests by a collection of measurements.
    In V5:
     - Simplify perftest.exp.
    In V4:
     - Rename MeasurementCPUTime to MeasurementCpuTime,
     - Add 'pass' in empty method,
     - Simplify string comparison in perftest.exp.
     - Rename GDB_PERFORMANCE to GDB_PERFTEST_MODE and rename
    In V3, there are some changes,
     - Add wall time measurement, cpu time measurement and vmsize
     - Rename SingleStatisticTestCase to TestCaseWithBasicMeasurements,
       which measures cpu time, wall time, and memory (vmsize).
     - GDB_PERFORMANCE=run|compile|both to control the mode of perf
     - New GDB_PERFORMANCE_TIMEOUT to specify the timeout.
     - Split proc prepare to proc compile and startup.
     - Disable GC while doing measurements.
    In V2, there are several changes to address Doug and Sanimir's
     - Add copyright header and docstring in perftest/
     - Remove
     - Fix docstring format.
     - Rename classes "SingleVariable" to "SingleStatistic".
     - Don't extend gdb.Function in class TestCase.  Add a new method run
       to run the test case so that we can pass parameters to test.
     - Allow to customize whether to warm up and to append test log.
     - Move time measurement into test harness.  Add a new class
       Measurement for a specific measurement and a new class Measure to
       measure them for a given test case.
     - A new class ResultFactory to create instances of TestResult.
     - New file lib/perftest.exp, which is to do some preparations and
       cleanups to simplify each *.exp file.
     - Skip compilation step if GDB_PERFORMANCE_SKIP_COMPILE is set.

commit 7636ccf9f2517bd3005c983de3c89f4861be04a5

    New make target 'check-perf' and new dir gdb.perf
    We add a new dir gdb.perf in testsuite for all performance tests.
    However, current 'make check' logic will either run dejagnu in
    directory testsuite or iterate all gdb.* directories which has *.exp
    files.  Both of them will run tests in gdb.perf.  We want to achieve:
     1) typical 'make check' should not run performance tests.  In each perf
        test case, GDB_PERFTEST_MODE is checked.  If it doesn't exist, return.
     2) run perf tests easily.  We add a new makefile target 'check-perf'.
