Eli Friedman e9692808b7 Make fast-isel miss counting in -stats and -fast-isel-verbose take terminators into account; since there are many fewer isel misses with recent changes, misses caused by terminators are more significant.

Johnny Chen 81a9df5b22 Let's also stick the svn info for the base directory into a file under 
the session directory, which also includes the command line used to invoke
the test suite.

Johnny Chen 112f5696fb Add truth value testing to those lldb Python objects with the IsValid() method definitions. 
object.__nonzero__(self) is called to implement truth value testing and the built-in operation bool(),
via a simple delegation to self.IsValid().

Change tests under python_api/lldbutil to utilize this mechanism.

Argyrios Kyrtzidis 8b7252a8b3 Fix a nasty bug where inside StringLiteralParser: 
1. We would assume that the length of the string literal token was at least 2
2. We would allocate a buffer with size length-2

And when the stars aligned (one of which would be an invalid source location due to stale PCH)
The length would be 0 and we would try to allocate a 4GB buffer.

Add checks for this corner case and a bunch of asserts.
(We really really should have had an assert for 1.).

Note that there's no test case since I couldn't get one (it was major PITA to reproduce),
maybe later.

John McCall 3597b6340c Revert r131434, my commit disabling the complete-object constructor 
optimization for abstract classes;  there was a misunderstanding, and
it turns out that there are no kexts which rely on this.

Tanya Lattner c7e291b354 vrev is incorrectly defined in the perfect shuffle table. The ordering is backwards (should be 0x3210 versus 0x1032) which exposed a bug when doing a shuffle on a 4xi16. I've attached a test case.

Alexis Hunt fa7afe2a05 Add some more tests. 
I have on that's #if 0'ed out, and I don't know why it's failing to
delete the constructor. I'd appreciate if someone familiar with access
control could look into ShouldDeleteDefaultConstructor - thanks.

Greg Clayton 5f5b2cad48 Fixed an issue that broke expression parsing related to backing up 
all register values. There is some junk that was appearing at the end
of the result the 'g' packet (read all register values). This function
was being called in:

bool
GDBRemoteRegisterContext::ReadAllRegisterValues (lldb::DataBufferSP &data_sp)

Then the packet data for the 'G' packet (write all registers) was being 
placed into "data_sp" so the:

bool
GDBRemoteRegisterContext::WriteAllRegisterValues (const lldb::DataBufferSP &data_sp)

could restore it. In attempting to clean up the extra junk at the end of this
packet data, the packet was getting truncated.

Jakob Stoklund Olesen 52375e6a01 Tweak cross-class coalescing to be more aggressive when the target class is small. 
The greedy register allocator has live range splitting and register class
inflation, so it can actually fully undo this join, including restoring the
original register classes.

We still don't want to do this for long live ranges, mostly because of the high
register pressure of there are many constrained live ranges overlapping.

Greg Clayton e6a9e439d4 Fixed the "mmap" to work on MacOSX/darwin by supplying the correct arguemnts. 
Modified ClangUserExpression and ClangUtilityFunction to display the actual
error (if one is available) that made the JIT fail instead of a canned 
response.

Fixed the restoring of all register values when the 'G' packet doesn't work
to use the correct data.

Greg Clayton d495c5340d Added an allocated memory cache to avoid having to allocate memory over and 
over when running JITed expressions. The allocated memory cache will cache 
allocate memory a page at a time for each permission combination and divvy up
the memory and hand it out in 16 byte increments.
