Shortcut open paren recognition for switch statements
Ignore all cpu-*.h files in mono/mini.
Use MonoBoolean instead of gboolean as an icall return type.
Use /proc/self/auxv for ARM feature detection when possible.

This is generally preferable because it works in QEMU chroots and
the information is significantly easier to process.

We still need to keep the /proc/cpuinfo code around, however, as
Android does not always allow access to /proc/self/auxv...

This patch also enhances the MONO_CPU_ARCH environment variable
to support the various new features we support.
convert some unit tests to modern style. (not really modern, just killing Assertion!)
a few more nunit test modernization.
Disable partial sharing for now, it breaks some tests on mt.
TimeSpan.TryParseExact should not try to parse null input.

TimeSpan.TryParseExact would previously throw a NullReferenceException constructing the Parser when it accesses the Length property of the input string. Microsoft's implementation returns false when null is passed as the input string to parse.

[corlib] Don't throw UnauthorizedAccessException from Path.GetTempFileName

The problem is sporadic mdoc test failures on Wrench/OS X:

I'm not sure why we're getting UnauthorizedAccessException exceptions,
nor do I particularly care; Path.GetTempFileName() should not be
throwing UnauthorizedAccessException; only IOException is documented:

	http://msdn.microsoft.com/en-us/library/system.io.path.gettempfilename.aspx

Update behavior to skip files that generate
UnauthorizedAccessException, and if we swallow short.MaxValue
exceptions wrap the UnauthorizedAccessException in an IOException so
that we conform to documented exceptional behavior.
