Subject: [PATCH 1/4] [clang][DebugInfo][NFC] Add createConstantValueExpression
helper
This patch factors out the code to create a DIExpression from
an APValue into a separate helper function.
This will be useful in a follow-up patch where we re-use this
logic elsewhere.

Subject: [PATCH 2/4] [clang][DebugInfo] Emit global variable definitions for
static data members with constant initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When an LLDB user asks for the value of a static data member, LLDB starts by
searching the Names accelerator table for the corresponding variable definition
DIE. For static data members with out-of-class definitions that works fine,
because those get represented as global variables with a location and making them
eligible to be added to the Names table. However, in-class definitions won’t get
indexed because we usually don't emit global variables for them. So in DWARF
we end up with a single `DW_TAG_member` that usually holds the constant initializer.
But we don't get a corresponding CU-level `DW_TAG_variable` like we do for
out-of-class definitions.
To make it more convenient for debuggers to get to the value of inline static data members,
this patch makes sure we emit definitions for static variables with constant initializers
the same way we do for other static variables. This also aligns Clang closer to GCC, which
produces CU-level definitions for inline statics and also emits these into `.debug_pubnames`.
The implementation keeps track of newly created static data members. Then in
`CGDebugInfo::finalize`, we emit a global `DW_TAG_variable` with a `DW_AT_const_value` for
any of those declarations that didn't end up with a definition in the `DeclCache`.
The newly emitted `DW_TAG_variable` will look as follows:
```
0x0000007b: DW_TAG_structure_type
DW_AT_calling_convention (DW_CC_pass_by_value)
DW_AT_name ("Foo")
...
0x0000008d: DW_TAG_member
DW_AT_name ("i")
DW_AT_type (0x00000062 "const int")
DW_AT_external (true)
DW_AT_declaration (true)
DW_AT_const_value (4)
Newly added
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
0x0000009a: DW_TAG_variable
DW_AT_specification (0x0000008d "i")
DW_AT_const_value (4)
DW_AT_linkage_name ("_ZN2t2IiE1iIfEE")
```
