DebugInfo: Hash DW_FORM_GNU_str_index as a string.

Found while adding type safety to the various DWARF enumerations (form,
attribute, tag, etc) that caused Clang to warn on an incompletely
covered switch. Converting the comment to a default/unreachable
uncovered this case of an unsupported form encoding. Seems we were
skipping fission strings entirely.

Optimize more linkonce_odr values during LTO.

When a linkonce_odr value that is on the dso list is not unnamed_addr
we can still look to see if anything is actually using its address. If
not, it is safe to hide it.

This patch implements that by moving GlobalStatus to Transforms/Utils
and using it in Internalize.

DebugInfo: Put each kind of constant (form, attribute, tag, etc) into its own enum for ease of use.

This allows various variables to be more self-documenting and easier to
debug by being of specific types without overlapping enum values.

X86 vector element shift-by-immediate instructions take i8 immediates. Make
the instruction defenitions and ISEL reflect this.

Prior to this patch these instructions took an i32i8imm, and the high bits were
dropped during encoding. This led to incorrect behavior for shifts by
immediates higher than 255. This patch fixes that issue by detecting large
immediate shifts and returning constant zero (for logical shifts) or capping
the shift amount at an encodable value (for arithmetic shifts).

Fix creating bitcasts between address spaces in SCEV.

The test before wasn't successfully testing this
since it was missing the datalayout piece to change
the size of the second address space.

DWARF type hashing: Handle multiple (including recursive) references to the same type

This uses a map, keeping the type DIE numbering separate from the DIEs
themselves - alternatively we could do things the way GCC does if we
want to add an integer to the DIE type to record the numbering there.
