Removing the @expectedFailurei386 decorator from test cases that now work as a result of the latest changes to Value.cpp

llvm-svn: 155419

This patch fixes a bug where LLDB was incorrectly setting the address-size on a DataExtractor to be sizeof(void*) when the ValueObject came out of the expression parser
This worked correctly for 64-bit targets, but broke down data formatters in i386 mode. The formatters would try to read pointers out of the frozen-dried objects,
but were unable to do so because they would try fetching 8 bytes from a DataExtractor with only 4 bytes in it. This patch fixes the issue by always making the pointer-size
for a DataExtractor match the target setting.

Added the ability to log a message with a backtrace when verbose logging is enabled to the Module class. Used this new function in the DWARF parser.

Fixed an issue where we get NULL compile units back from the symbol vendor. We need symbol vendors to be able to quickly give an estimate of the compile units that they have without having to fully vette them first, so anyone getting compile units from a module should be able to deal with a NULL compile unit being returned for a given index.

on X86 Atom. Some of our tests failed because the tail merging part of
the BranchFolding pass was creating new basic blocks which did not
contain live-in information. When the anti-dependency code in the Post-RA
scheduler ran, it would sometimes rename the register containing
the function return value because the fact that the return value was
live-in to the subsequent block had been lost. To fix this, it is necessary
to run the RegisterScavenging code in the BranchFolding pass.

This patch makes sure that the register scavenging code is invoked
in the X86 subtarget only when post-RA scheduling is being done.
Post RA scheduling in the X86 subtarget is only done for Atom.

This patch adds a new function to the TargetRegisterClass to control
whether or not live-ins should be preserved during branch folding.
This is necessary in order for the anti-dependency optimizations done
during the PostRASchedulerList pass to work properly when doing
Post-RA scheduling for the X86 in general and for the Intel Atom in particular.

The patch adds and invokes the new function trackLivenessAfterRegAlloc()
instead of using the existing requiresRegisterScavenging().
It changes BranchFolding.cpp to call trackLivenessAfterRegAlloc() instead of
requiresRegisterScavenging(). It changes the all the targets that
implemented requiresRegisterScavenging() to also implement
trackLivenessAfterRegAlloc().  

It adds an assertion in the Post RA scheduler to make sure that post RA
liveness information is available when it is needed.

It changes the X86 break-anti-dependencies test to use –mcpu=atom, in order
to avoid running into the added assertion.

Finally, this patch restores the use of anti-dependency checking
(which was turned off temporarily for the 3.1 release) for
Intel Atom in the Post RA scheduler.

Patch by Andy Zhang!

When building LLVM on Linux with libc++ with CMake TIME_WITH_SYS_TIME is
undefined, and HAVE_SYS_TIME_H is defined. This ends up including
sys/time.h but not time.h. Unix/TimeValue.inc requires time.h for asctime_r
and localtime. libstdc++ seems to include time.h anyway, but libc++ does
not.

Fix this by always including time.h
