Logan Chien 855b17d1bc Update code listings in LLVM tutorial.
Several LLVM headers are moved.  The code listings in
LLVM tutorial are not updated yet.

This CL removes the code replica in the .rst, and replace
them with a literalinclude directive, so that sphinx can
include the latest code automatically.

Shuxin Yang 140d592d84 Fix a potential bug in r183584.
r183584 tries to derive some info from the code *AFTER* a call and apply
these derived info to the code *BEFORE* the call, which is not always safe
as the call in question may never return, and in this case, the derived
info is invalid.
  
  Thank Duncan for pointing out this potential bug.

Sean Silva 4bf5c4b746 Don't artifically restrict input object size.
sys::IdentifyFileType is already conscious of the length, and
object_error::invalid_file_type is returned below anyway if
sys::IdentifyFileType doesn't recognize the file.

Anna Zaks 22895473af [analyzer; alternate edges] Fix the edge locations in presence of macros.
We drew the diagnostic edges to wrong statements in cases the note was on a macro.
The fix is simple, but seems to work just fine for a whole bunch of test cases (plist-macros.cpp).

Also, removes an unnecessary edge in edges-new.mm, when function signature starts with a macro.

Quentin Colombet 249cb6756c Reapply r183552. This time, use a standard type for the option to avoid template
instantiation issue with non-standard type.

Add a backend option to warn on a given stack size limit.
Option: -mllvm -warn-stack-size=<limit>
Output (if limit is exceeded):
warning: Stack size limit exceeded (<actual size>) in <functionName>.

The longer term plan is to hook that to a clang warning.

Vincent Lejeune d1a9d18120 R600: Use a refined heuristic to choose when switching clause
This is using a hint from AMD APP OpenCL Programming Guide with
empirically tweaked parameters.
I used Unigine Heaven 3.0 to determine best parameters on my system
(i7 2600/Radeon 6950/Kernel 3.9.4) the benchmark :
it went from 38.8 average fps to 39.6, which is ~3% gain.
(Lightmark 2008.2 gain is much more marginal: from 537 to 539)

There is no lit test provided as the parameter were determined
empirically and it it would be nearly impossiblet to find a test
program that check for optimal behavior.

Shuxin Yang bd254f2601 Fix an assertion in MemCpyOpt pass.
The MemCpyOpt pass is capable of optimizing:
      callee(&S); copy N bytes from S to D.
    into:
      callee(&D);
subject to some legality constraints. 

  Assertion is triggered when the compiler tries to evalute "sizeof(typeof(D))",
while D is an opaque-typed, 'sret' formal argument of function being compiled.
i.e. the signature of the func being compiled is something like this:
  T caller(...,%opaque* noalias nocapture sret %D, ...)

  The fix is that when come across such situation, instead of calling some
utility functions to get the size of D's type (which will crash), we simply
assume D has at least N bytes as implified by the copy-instruction.
