For some LLVM-as-library uses it is convenient to create a
subclass of TargetMachine which "forwards" all operations to an
existing internal TargetMachine member variable. In the usage context the
specific-machine class derived from TargetMachine is not visible,
only a reference to the generic base class TargetMachine. Although
getSubtargetImpl() is public in specific-machine classes derived from
TargetMachine, the TargetMachine class unfortunately has
getSubtargetImpl() protected (and accessing non-const members makes
abusing getSubtarget() unsuitable). Making it public in the base class
allows this forwarding pattern.

Configure: if we compile with clang, check that it is not broken
Some linux distibutions (for example, Mageia 2, Fedora 17) ship Clang that is
essentially broken for the end user. Clang can not find or compile libstdc++
headers.
The issue is that our configure prefers clang over gcc, thus selecting a broken
Clang when a working GCC is available.
Now we detect this issue by compiling a simple program. If it does not
compile, configure stops with an error suggesting the user to select a
different compiler.

fp128 is almost but not quite completely illegal as a type on AArch64. As a

targets to do this (without duplicating code), as the relevant functions are
