This is another TLC patch for separating code for the Darwin and ELF ABIs
for the PowerPC target, and factoring the results. This will ease future
maintenance of both subtargets.
PPCTargetLowering::LowerCall_Darwin_Or_64SVR4() has grown a lot of special-case
code for the different ABIs, making maintenance difficult. This is getting
worse as we repair errors in the 64-bit ELF ABI implementation, while avoiding
changes to the Darwin ABI logic. This patch splits the routine into
LowerCall_Darwin() and LowerCall_64SVR4(), allowing both versions to be
significantly simplified. I've factored out chunks of similar code where it
made sense to do so. I also performed similar factoring on
LowerFormalArguments_Darwin() and LowerFormalArguments_64SVR4().

Improved support for language types as command
options:
- added help ("help language") listing the
possible options;
- added the possibility of synonyms for language
names, in this case "ObjC" for "Objective-C";
and
- made matching against language names case
insensitive.
This should improve discoverability.

Ugly ugly hack for libstdc++-4.6 and libstdc++-4.7 compatibility. These
libraries have an incorrect definition of std::common_type (inherited from a
bug in the standard -- see LWG issue 2141), whereby they produce reference
types when they should not.
If we instantiate a typedef named std::common_type<...>::type, which is defined
in a system header as decltype(... ? ... : ...), and the decltype produces a
reference type, convert it to the non-reference type. (This doesn't affect any
LWG2141-conforming implementation of common_type, such as libc++'s, because the
default implementation of common_type<...>::type isn't supposed to produce a
reference type.)
This is horrible. I'm really sorry. :( Better ideas appreciated!

[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.
