Lets rename codeOriginIndex to callSiteIndex and get rid of CallFrame::Location.
https://bugs.webkit.org/show_bug.cgi?id=148213

Reviewed by Filip Pizlo.

This patch introduces a struct called CallSiteIndex which is
used as a wrapper for a 32-bit int to place things in the tag for ArgumentCount 
in the call frame. On 32-bit we place Instruction* into this slot for LLInt and Basline.
For 32-bit DFG we place a an index into the code origin table in this slot.
On 64-bit we place a bytecode offset into this slot for LLInt and Baseline.
On 64-bit we place the index into the code origin table in this slot in the
DFG/FTL.

This patch also gets rid of the encoding scheme that describes if something is a
bytecode index or a code origin table index. This information can always
be determined based on the CodeBlock's' JITType.

StructureStubInfo now also has a CallSiteIndex which it stores to
the call frame when making a call.
