Neil Hickey f603672b5c Improve handling of floating point literals in OpenCL to only use double precision if the target supports fp64.
This change makes sure single-precision floating point types are used if the 
cl_fp64 extension is not supported by the target.

Also removed the check to see whether the OpenCL version is >= 1.2, as this has
been incorporated into the extension setting code.

Alexey Bader 0ea075328e [OpenCL] Override supported OpenCL extensions with -cl-ext option
Summary:
This patch adds a command line option '-cl-ext' to control a set of
supported OpenCL extensions. Option accepts a comma-separated list
of extensions prefixed with '+' or '-'.

It can be used together with a target triple to override support for some
extensions:

  // spir target supports all extensions, but we want to disable fp64
  clang -cc1 -triple spir-unknown-unknown -cl-ext=-cl_khr_fp64

Special 'all' extension allows to enable or disable all possible
extensions:

  // only fp64 will be supported
  clang -cc1 -triple spir-unknown-unknown -cl-ext=-all,+cl_khr_fp64

Patch by asavonic (Andrew Savonichev).
