Rafael Espindola c823f00ed1 Use std::list so that we have a stable iterator. 
I will try to avoid creating these std::strings, but for now this gets
the tests passing with libc++.

Enrico Granata 3189891857 <rdar://problem/13925432> 
A user request such as: memory read -fc -s10 -c1 *charPtrPtr would cause us to crash upon trying to read 1 char of size 10 from memory
This request is now translated into: memory read -fc -s1 -c10 *charPtrPtr (i.e. read 10 chars of size 1 from memory) which is probably also what the user originally wanted

Hal Finkel c5211291f1 Fix PPC branch selection for counter-based branches 
Although I had added some support for the BDZ/BDNZ branches into the selector
(in r158204), I had not correctly adjusted the condition at the top of the
loop. As a result, these branches were still essentially unsupported.

This fixes PR16086. Unfortunately, any test case would be very large (because
it would need to force the loop backedge to exceed the range of the 16-bit
immediate).

Daniel Jasper 2a250b8b49 Let clang-format move the cursor appropriately. 
With this patch, clang-format will try to keep the cursor at the
original code position in editor integrations (implemented for emacs and
vim). This means, after formatting, clang-format will try to keep the
cursor on the same character of the same token.

Tobias Grosser 04be044af5 Remove .htaccess file 
It was initially committed to allow people to get a list of the files used
or generated in the matmul tutorial. Since the documentation does now
point people to the directory in their git checkout, it is not necessary anymore
to make a directory listing available. Especially, as this never worked and
recently the LLVM web server does not deliver files in this directory at all
due to the unsupported .htaccess file.

Ulrich Weigand 7c81c7c66b Alternative fix for problem addressed in r182233 
Revision r182233 partially reverted the change in r181200 to simplify
JIT unif test #ifdefs, because that change caused a link error on some
host operating systems where the export list requires the following
symbols to be defined:

 JITTest_AvailableExternallyFunction
 JITTest_AvailableExternallyGlobal

As discussed on the list, the commit reverts r182233 (and re-installs
the full r181200 change), and instead fixes the link problem by moving
those two symbols to the top of the file and unconditionally defining
them.

Richard Smith b39b9d5735 In -ast-dump, only dump comments when dumping the actual Decl to which they 
attach, rather than merging all comments on the declaration chain. This gives a
more faithful dump, and has the side benefit of unbreaking uses of dump() from
within AST deserialization (where the redeclaration chain may not be sane).
