by instruction address from DWARF.

Add --inlining flag to llvm-dwarfdump to demonstrate and test this functionality,
so that "llvm-dwarfdump --inlining --address=0x..." now works much like
"addr2line -i 0x...", provided that the binary has debug info
(Clang's -gline-tables-only *is* enough).

If an allocation has a must-alias relation to the access pointer, we treat it
as a Def.  Otherwise, without this check, the code here was just skipping over
the allocation call and ignoring it.  I noticed this by inspection and don't
have a specific testcase that it breaks, but it seems like we need to treat
a may-alias allocation as a Clobber.

By calling cindex.Config.set_library_path(path) or
cindex.Config.set_library_file(file) it is possible to specify from where
we load libclang. This fixes an open FIXME.

We also point the user to these functions, in case libclang can not be
loaded sucessfully.

This change adds detection of C++ headers and libraries paths when
building with the standalone toolchain from Android NDK. They are in a
slightly unusual place.

Fixs PR13719.

llvm-svn: 163107

This code used to only handle malloc-like calls, which do not read memory.
r158919 changed it to check isNoAliasFn(), which includes strdup-like and
realloc-like calls, but it was not checking for dependencies on the memory
read by those calls.

These values are used by the ConvertToMCInst() function to index into the
ConversionTable.  The values are also needed to call the GetMCInstOperandNum()
function.

For example, the ARM target does not have efficient ISel handling for vector
selects with scalar conditions. This patch adds a TLI hook which allows the
different targets to report which selects are supported well and which selects
should be converted to CF duting codegen prepare.

tsan: do not crash with obscure message if a user passes invalid arguments to malloc/free/memset/etc

We update until we hit a fixpoint. This is probably slow but also
slightly simplifies the code. It should also fix the occasional
invalid domtrees observed when building with expensive checking.

I couldn't find a case where this had a measurable slowdown, but
if someone finds a pathological case where it does we may have
to find a cleverer way of updating dominators here.

Thanks to Duncan for the test case.
