159c735f7b APFloat cleanup: Remove now unused "arithmeticOK" logic.

fce241d76f APFloat cleanup: Remove now unused fields "sign2" and "exponent2".

69c9c8c4cf Implement arithmetic on APFloat with PPCDoubleDouble semantics by 
treating it as if it were an IEEE floating-point type with 106-bit
mantissa.

This makes compile-time arithmetic on "long double" for PowerPC
in clang (in particular parsing of floating point constants)
work, and fixes all "long double" related failures in the test
suite.

81e35ff722 Support: Don't remove special files on signals. 
- Similar to Path::eraseFromDisk(), we don't want LLVM to remove things like
   /dev/null, even if it has the permission.

7bbd6e366b Support for generating ELF objects on Windows. 
This adds 'elf' as a recognized target triple environment value and overrides the default generated object format on Windows platforms if that value is present.  This patch also enables MCJIT tests on Windows using the new environment value.

bec3ce0cb5 The assumption that /proc/self/exe always exists is incorrect. 
For example, under a Linux chroot, /proc/ might not be mounted.
Therefor, we test if this file exist. If it is the case, use it (the current
behavior). Otherwise, we fall back to the detection used by *BSD.

The issue has been reported initially on the Debian bug tracker:
http://bugs.debian.org/674588

43bf70986b Rename ANDROIDEABI to Android. 
Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".

Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.
