Evgeniy Stepanov edc91428a2 Add -fno-assume-sane-operator-new when building with MSan.
A workaroudn for PR16386. MSan's operator new aften has side-effects that are
miscompiled without this flag.

Reid Kleckner 724c21c05b [Driver] Remove the using namespace directives from headers
This adds a bunch of llvm::opt name specifiers to all the uses of types
from that namespace.

Reid Kleckner 898229ab4b [Driver] Refactor clang driver to use LLVM's Option library
The big changes are:
- Deleting Driver/(Arg|Opt)*
- Rewriting includes to llvm/Option/ and re-sorting
- 'using namespace llvm::opt' in clang::driver
- Fixing the autoconf build by adding option everywhere

As discussed in the review, this change includes using directives in
header files.  I'll make follow up changes to remove those in favor of
name specifiers.

Sergey Matveev 1814e9eae3 Add -fsanitize=leak to driver options.
If -fsanitize=leak is specified, link the program with the
LeakSanitizer runtime. Ignore this option when -fsanitize=address is specified,
because AddressSanitizer has this functionality built in.

Richard Smith 539e4a77bb ubsan: Emit bounds checks for array indexing, vector indexing, and (in really simple cases) pointer arithmetic. This augments the existing bounds checking with language-level array bounds information.

Chad Rosier ae229d599b [ubsan] Implement the -fcatch-undefined-behavior flag using a trapping
implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.

The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred.  Eventually, the -fcatch-undefined-behavior' flag will be removed.

Alexey Samsonov 29524a9871 Add top-level Clang flag -f(no-)sanitize-address-zero-base-shadow that makes AddressSanitizer use bottom of the address space for the shadow memory. On Linux it can be used with -fPIE/-pie to improve performance.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Alexey Samsonov 9ab73626fc Add Clang flags -fsanitize-blacklist and -fno-sanitize-blacklist. Make this flag usable for ASan. Blacklisting can be used to disable sanitizer checks for particular file/function/object.

Alexey Samsonov 0e96becfb1 This patch exposes to Clang users three more sanitizers are experimental features of ASan:
1) init-order sanitizer: initialization-order checker.
Status: usable, but may produce false positives w/o proper blacklisting.
2) use-after-return sanitizer
Status: implemented, but heavily understed.
Should be optional, as it significanlty slows program down.
3) use-after-scope sanitizer
Status: in progress.
