8172c32318 Add an --enable-backtraces option to configure to determine 
whether or not we want to print out backtrace information. Useful
for libraries that don't need backtrace information on a crash.

93c7ec80b7 Fix Doxygen issues: 
* wrap code blocks in \code ... \endcode;
* refer to parameter names in paragraphs correctly (\arg is not what most
  people want -- it starts a new paragraph);
* use \param instead of \arg to document parameters in order to be consistent
  with the rest of the codebase.

5dc162e9e0 Rename ANDROIDEABI to Android. 
Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".

Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

5aa2b024d7 Add some __builtin_expect magic to StringMap. 
Tombstones and full hash collisions are rare, mark the "empty"
and "no collision" paths as likely. The bug in simplifycfg
that prevented the hints from being picked during selfhost
up was fixed recently :)

clang support for Freescale cross-compile configurations.

f4e550e004 Initial commit of new FileOutputBuffer support class. 
Since the llvm::sys::fs::map_file_pages() support function it relies on
is not yet implemented on Windows, the unit tests for FileOutputBuffer 
are currently conditionalized to run only on unix.

324d91f181 reimplement truncate() to make it optimal. 
It is optimal at least up to 7 bits (I've tested all such cases)
This change to truncate() allows a little simplification to the multiplication code,
and it also makes multiplication optimal :)

d2b344c685 This patch fixes 8 out of 20 unexpected failures in "make check" 
when run on an Intel Atom processor. The failures have arisen due
to changes elsewhere in the trunk over the past 8 weeks or so.

These failures were not detected by the Atom buildbot because the
CPU on the Atom buildbot was not being detected as an Atom CPU.
The fix for this problem is in Host.cpp and X86Subtarget.cpp, but
shall remain commented out until the current set of Atom test failures
are fixed.

Patch by Andy Zhang and Tyler Nowicki!

4cbb37098a In MemoryBuffer::getOpenFile() don't verify that the mmap'ed 
file buffer is null-terminated.

If the file is smaller than we thought, mmap will not allow dereferencing
past the pages that are enough to cover the actual file size,
even though we asked for a larger address range.
