Fix FileCheck crash when empty prefix is passed.

Move the bitcode error enum to the include directory.

This will let users in other libraries know which error occurred. In particular,
it will be possible to check if the parsing failed or if the file is not
bitcode.

Support LIBRARY_PATH on all Darwin targets.

r197490 changed the behavior of LIBRARY_PATH to try to match GCC's behavior
for cross compilers and make clang work better on "bare metal" targets.
Unfortunately that change is breaking a number of MacPorts projects because
the LIBRARY_PATH environment variable is being ignored when compiling on a
64-bit host for a 32-bit target. Because the host and target architectures
differ, isCrossCompiling returns true. This does not make sense for Darwin,
where multiple architectures are supported natively via "fat" Mach-O slices
and where development is generally done against SDKs regardless. This patch
fixes the problem by overriding isCrossCompiling to return false for Darwin
toolchains.

Use the most up to date dsymutil on Darwin, not the one in /usr/bin/dsymutil.

Revert "Fix test case in r214190. (It failed on my end.)"

This was an accident.

Base regex code on char_class_type.

__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.

This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

Small gold plugin simplifications.

* Use a range loop.
* Store the extra options as "const char *".

Fix typo.

Fix PR10177 where non-type template arguments to alias templates are not marked as used in 
dependent contexts. The fix actually forces non-dependent names to be checked at template 
definition time as expected from the standard.

Install the `obj2yaml` and `yaml2obj` utilities together with other LLVM tools.

[Debug Info] update testing case due to change in DIBuilder.

This is the paired commit with llvm r214189.

[Debug Info] remove DITrivialType and use null to represent unspecified param.

Per feedback on r214111, we are going to use null to represent unspecified
parameter. If the type array is {null}, it means a function that returns void;
If the type array is {null, null}, it means a variadic function that returns
void. In summary if we have more than one element in the type array and the last
element is null, it is a variadic function.

Fix the sort of expected order in the reader to correctly return `false`
