The ISD::FPOW and ISD::FSINCOS opcodes default to Legal, but there
is no legal instruction for those on SystemZ.  This could cause
LLVM internal errors.  Fixed by setting the operation action to
Expand for those opcodes.

Also added test cases for all other LLVM IR intrinsics that should
generate a library call.  (Those already work correctly since the

Restore "Function bitcode index in Value Symbol Table and lazy reading support"

This reverts commit r247898 (which reverted r247894).

Patch fixed to address two issues exposed by buildbots:
- unused variable warning in NDEBUG mode
- std::initializer_list lifetime issue causing test failures

Original Summary:
Support for including the function bitcode indices in the Value Symbol
Table. This requires writing the VST after the function blocks, which in
turn requires a new VST forward declaration record encoding the offset of
the full VST (which is backpatched to contain the offset after the VST
is written).

This patch also enables the lazy function reader to use the new function
indices out of the VST. This support will be used by ThinLTO as well, which
will be in a follow on patch. Backwards compatibility with older bitcode
files is maintained.

A new test is also included.

The bitcode format (used for the lazy reader as well as the upcoming
ThinLTO patches) came out of discussions with Duncan and others and is
described here:
