New Revision: 1feb7af046889728233e67e3163ab30020207bb2
URL: https://github.com/llvm/llvm-project/commit/1feb7af046889728233e67e3163ab30020207bb2
DIFF: https://github.com/llvm/llvm-project/commit/1feb7af046889728233e67e3163ab30020207bb2.diff
LOG: [clangd] support expanding `decltype(expr)`
Enable the existing tweak `ExpandAutoType` to expand
`decltype(expr)`, e.g.
```
decltype(0) i;
```
will expand to
```
int i;
```
Therefore, rename the tweak `ExpandAutoType` to `ExpandDeducedType`.
This patch also fixes some nits,
* avoid replacing reference to a function
* avoid replacing array types and reference to an array
Fixes https://github.com/clangd/clangd/issues/1456
