744611f9ba Disable accelerator tables when compiling with LTO.
LTO doesn't generate correct accelerator tables. This is due to the general lack
correct of debug info for LTO. Disable it when using LTO.

aa71657749 Per discussion on cfe-commits, treat -faddress-sanitizer,
-fno-address-sanitizer, -fthread-sanitizer, -fno-thread-sanitizer, and
-fcatch-undefined-behavior as deprecated: produce a warning if they are used
pointing to the corresponding -fsanitize= option. In passing add the missing
'-' to some diagnostics.

b1b0ab41e7 Use the individual -fsanitize=<...> arguments to control which of the UBSan
checks to enable. Remove frontend support for -fcatch-undefined-behavior,
-faddress-sanitizer and -fthread-sanitizer now that they don't do anything.

52be619c84 Add -fsanitize=<sanitizers> argument to driver and frontend, and add
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the
various UBSan checks to be enabled and disabled separately. Right now, the
different modes can't be combined, but the intention is that combining UBSan
and the other sanitizers will be permitted in the near future.

Currently, the UBSan checks will all be enabled if any of them is; that will be
fixed by the next patch.

616e8a5c0b [driver] Older versions of ld expect '-L<dir>' not '-L <dir>'. In Xcode4 and
later, '-L <dir>' is allowed, but rewrite these in the driver as '-L<dir>' to
maintain backward compatibility.  The same is true for the -I option.

929fccd476 [Options] Add prefixes to options.
Each option has a set of prefixes. When matching an argument such as
-funroll-loops. First the leading - is removed as it is a prefix. Then
a lower_bound search for "funroll-loops" is done against the option table by
option name. From there each option prefix + option name combination is tested
against the argument.

This allows us to support Microsoft style options where both / and - are valid
prefixes. It also simplifies the cases we already have where options come in
both - and -- forms. Almost every option for gnu-ld happens to have this form.

058666a8d0 Driver: Link crtfastmath.o if it's available and -ffast-math is specified.
crtfastmath.o contains routines to set the floating point flags to a faster,
unsafe mode. Linking it in speeds up code dealing with denormals significantly
(PR14024).

For now this is only enabled on linux where I can test it and crtfastmath.o is
widely available. We may want to provide a similar file with compiler-rt
eventually and/or enable it on other platforms too.

3b2000fcac During LTO, we call 'dsymutil' when we compile source files. This necessitates
clang specifying a temporary file that it later cleans up so that it can survive
the linking stage. However, when we compile object files during LTO we don't
call 'dsymutil'. That's done at a different stage (if at all). We rely upon the
linker to specify a unique name for the temporary file it generates.

c9cde48f3a Wrong crtbegin/crtend pair used for PIE on Android.
Android uses the same flavour of crt*.o for PIE and non-PIE executables, and a

for non-PIE executables, and another for both PIE executables and DSOs.
