6131b44183
Rework the way we handle template instantiation for
...
implicitly-generated AST nodes. We previously built instantiated nodes
for each of these AST nodes, then passed them on to Sema, which was
not prepared to see already-type-checked nodes (see PR5755). In some
places, we had ugly workarounds to try to avoid re-type-checking
(e.g., in VarDecl initializer instantiation).
Now, we skip implicitly-generated nodes when performing instantiation,
preferring instead to build just the AST nodes that directly reflect
what was written in the source code. This has several advantages:
- We don't need to instantiate anything that doesn't have a direct
correlation to the source code, so we can have better location
information.
- Semantic analysis sees the same thing at template instantiation
time that it would see for a non-template.
- At least one ugly hack (VarDecl initializers) goes away.
Fixes PR5755.

Revise scalar replacement to be more flexible about handle bitcasts and GEPs.
...
While scanning through the uses of an alloca, keep track of the current offset
relative to the start of the alloca, and check memory references to see if
the offset & size correspond to a component within the alloca. This has the
nice benefit of unifying much of the code from isSafeUseOfAllocation,
isSafeElementUse, and isSafeUseOfBitCastedAllocation. The code to rewrite
the uses of a promoted alloca, after it is determined to be safe, is
reorganized in the same way.
Also, when rewriting GEP instructions, mark them as "in-bounds" since all the
indices are known to be safe.
