Sean Callanan 8a518d5b54 Updated LLVM/Clang to pull in a variety of type
importation fixes, reducing the amount of requests
made to LLDB for unknown types and increasing 
fidelity of the expression parser.

Sean Callanan 80c48c10d0 Made the IR interpreter more robust in the presence
of arbitrary pointers, allowing direct dereferences
of literal addresses.  Also disabled special-cased
generation of certain expression results (especially
casts), substituting the IR interpreter.

Nick Lewycky 90a47b127b Try to be exceedingly clever and make this test work properly whether it's run
under bash or under cmd.exe.

Douglas Gregor 60060d6f8f Treat the Microsoft/Borland keyword "__except" as a context-sensitive
keyword, because both libstdc++ and libc++ use "__except" as an
identifier. Fixes <rdar://problem/10322555>.

Sean Callanan 95e74be193 I added a new function to DeclContext called
addDeclInternal().  This function suppresses any
calls to FindExternalVisibleDeclsByName() while
a Decl is added to a DeclContext.  This behavior
is required for the ASTImporter, because in the
case of the LLDB client the ASTImporter would be
called recursively to import the visible decls,
which leads to assertions because the recursive
call is seeing partially-formed types.

I also modified the ASTImporter to use
addDeclInternal() in all places where it would
otherwise use addDecl().  This fix should not
affect the rest of Clang, passes Clang's
testsuite, and fixes several serious LLDB bugs.

Nick Lewycky ba743b75cb Take DW_AT_comp_dir from $PWD when it's present and starts with a '/'. This is
closer to what GCC does, except that GCC also checks that the inodes for $PWD
and '.' match.

Johnny Chen 7f63fdaa74 Add a benchmark for measuring start up delays of lldb, including:
o create a fresh target; and
o set the first breakpoint

Example (using lldb to set a breakpoint on lldb's Driver::MainLoop function):

./dotest.py -v +b -x '-F Driver::MainLoop()' -p TestStartupDelays.py

...

1: test_startup_delay (TestStartupDelays.StartupDelaysBench)
   Test start up delays creating a target and setting a breakpoint. ... 
lldb startup delays benchmark:
create fresh target: Avg: 0.106732 (Laps: 15, Total Elapsed Time: 1.600985)
set first breakpoint: Avg: 0.102589 (Laps: 15, Total Elapsed Time: 1.538832)

Greg Clayton 97fbc34276 Fixed some issues where we might not have one of the new apple accelerator
tables (like the .apple_namespaces) and it would cause us to index DWARF that
didn't need to be indexed.

Updated the MappedHash.h (generic Apple accelerator table) and the DWARF
specific one (HashedNameToDIE.h) to be up to date with the latest and
greatest hash table format.

Johnny Chen ff7fc9cfa4 Breakpoint specification can have the form '-n main', so it's not a good idea to

Richard Smith fe2750db42 Add -Wc++98-compat diagnostics for jumps which bypass initialization of non-POD
but trivially constructible and destructible variables in C++11 mode. Also
incidentally improve the precision of the wording for jump diagnostics in C++98
mode.

Duncan Sands 9341b50c07 Reset the system compiler each time we start a new flavour. Otherwise
the last compiler built for the previous flavour is used for the next,
for example the Debug clang compiler was being used for the initial build
of the Release LLVM.  Flavors should be independent of each other.  This
especially matters if the compiler built for the previous flavour doesn't
actually work!

Lang Hames aaf379027d Haven't yet found a nice way to handle TargetData verification in the
AsmParser. This patch adds validation for target data layout strings upon
construction of TargetData objects. An attempt to construct a TargetData object
from a malformed string will trigger an assertion.

Douglas Gregor f4ef4d2ec5 There's no point in marking a declaration invalid just because it
shadows a template parameter. Complain about the shadowing (or not,
under -fms-extensions), but don't invalidate the declaration. Merely
forget about the template parameter declaration.
