Richard Smith 1629da95fe ubsan: Add -fsanitize=bool and -fsanitize=enum, which check for loads of
bit-patterns which are not valid values for enumerated or boolean types.
These checks are the ubsan analogue of !range metadata.

Hal Finkel 061f1653e6 Add -fslp-vectorize to enable bb-vectorize
Add -fslp-vectorize (with -ftree-slp-vectorize as an alias for gcc compatibility)
to provide a way to enable the basic-block vectorization pass. This uses the same
acronym as gcc, superword-level parallelism (SLP), also common in the literature,
to refer to basic-block vectorization.

Nadav suggested this as a follow-up to the adding of -fvectorize.

Rafael Espindola c720d46ed7 Add tests for a corner case of when to relax all instructions:
We don't want to relax all instructions in

$ clang -c test.s

since most users don't pass -O when using the driver to assemble.

On the other hand, -save-temps should not change the output unnecessary, so in

$ clang -c test.c -save-temps

we should relax all instructions.

David Chisnall a87d85994b long double should be 64 bits on FreeBSD/MIPS64. It possibly should be on
Linux too, as I think we inherited it from there.  The ABI spec says 128-bit,
although I think SGI's compiler on IRIX may be the only thing ever to support
this.

Chandler Carruth 210c77b38c Add -whole-archive around the ASan runtime archive in the link command.
This ensures that even though it comes first, we pick up its .o files.
Note that if we can use this (or something similar / equivalent) on
other platforms, we could potentially remove
ReplaceOperatorsNewAndDelete from the ASan runtimes.

We should probably do something similar for TSan and MSan as well.

Matt Beaumont-Gay 35439dff76 Currently, with -fsanitize=address, the driver appends libclang_rt.asan.a to
the link command. This all works fine when the driver is also responsible for
adding -lstdc++ to the link command. But, if -lstdc++ (or libstdc++.a, etc) is
passed explicitly to the driver, the ASan runtime will appear in the link
command after the standard library, leading to multiple-definition errors for
the global 'operator new' and 'operator delete'. Fix this in a painfully
simple way, by inserting libclang_rt.asan.a at the start of the link command
instead of the end.

If we need to do something more clever, we can walk the link command looking
for something that resembles libstdc++ and insert libclang_rt.asan.a as late
as possible, but the simple solution works for now.

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.

Chandler Carruth 05fb585a36 Fix the '-fuse-init-array' option to actually be an option.
Previously, this flag to CC1 was never exposed at the clang driver
layer, and if you happened to enable it (by being on Android or GCC 4.7
platform), you couldn't *disable* it, because there was no 'no' variant.
The whole thing was confusingly implemented.

Now, the target-specific flag processing gets the driver arg list, and
we use standard hasFlag with a default based on the GCC version and/or
Android platform. The user can still pass the 'no-' variant to forcibly
disable the flag, or pass the positive variant to clang itself to enable
the flag.

The test has also been substantially cleaned up and extended to cover
these use cases.
