Saleem Abdulrasool aea65e9b13 Driver: add -m{,no-}long-calls support
This mirrors the GCC option for the ARM backend.  This option enables the
backend option "-enable-arm-long-calls".  The default behaviour is that this is
disabled due to the slight overhead of the generated calls.

If the target of jumps are greater than 64M range of offset-based jumps, then
the target address must be loaded into a register to make an indirect jump.  The
backend support for this has been present, but was not previously controllable
by the proper flag.

Richard Smith 4244ea9ca1 [ubsan] Don't add a --dynamic-list for ubsan symbols when building a shared
library. That results in the linker resolving all references to weak symbols in
the DSO to the definition from within that DSO. Ironically, this rarely causes
observable problems, except that it causes ubsan's own dynamic type check to
spuriously fail (because we fail to properly merge type_info object names).

Alexey Samsonov b01f936ffe [ASan] Split static ASan runtime in two parts: asan and asan_cxx.
asan_cxx containts replacements for new/delete operators, and should
only be linked in C++ mode. We plan to start building this part
with exception support to make new more standard-compliant.

Simon Atanasyan 60280b4e65 [Driver] Do not lose already detected set of toolchain's multilibs while
iterating over different library path suffixes and different library versions.

To find the most appropriate library for the given command line flags we
iterate over a set of disk paths. Before probe each path the already
detected set of multilibs are cleared. If the set of paths contains
existing paths which do not satisfy command line flags or do not contain
necessary libraries and object files at all we might lose found multilibs.

The patch updates variables which hold detected multilibs if we really find
a new multilib matches command line flags.

The patch reviewed by Jon Roelofs.

Saleem Abdulrasool 62849c677c Driver: parse -mcmodel earlier
This addresses an existing FIXME item in the driver.  The code model flag was
parsed in the actual tool rather than in the driver.  This was problematic since
the value may be invalid.  In that case, we would silently treat it as a default
value in non-assert builds, and abort in assert builds.  Add a check in the
driver to validate that the value being passed is valid, and if not provide a
proper error message.

Rafael Espindola b5b622a03c Drop non-cfi assembly support from clang.
After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and
always print assembly that uses cfi directives.

In llvm, MC itself supports cfi since the end of 2010 (support started
in r119972, is reported in the 2.9 release notes).

In binutils the support has been around for much longer. It looks like
support started to be added in May 2003. It is available in 2.15
(31-Aug-2011, 2.14 is from 12-Jun-2003).
