In the past we had a hardcoded list of DOM methods in the label matchers.
This modification lets us replace 100 explicit labels of this type:
```
[[labels]]
name = "Document.querySelector"
funcPrefixes = [
"mozilla::dom::Document_Binding::querySelector(",
"blink::`anonymous namespace'::v8_document::QuerySelectorOperation",
"blink::(anonymous namespace)::v8_document::QuerySelectorOperation",
"WebCore::jsDocumentPrototypeFunction_querySelector",
]
```
with one auto label of this type:
```
[[auto_labels]]
nameTemplate = "{Class}.{method}"
funcPrefixTemplates = [
"mozilla::dom::{Class}_Binding::{method}(",
"blink::`anonymous namespace'::v8_{Class:blink_snake}::{method:pascal}Operation",
"blink::(anonymous namespace)::v8_{Class:blink_snake}::{method:pascal}Operation",
"WebCore::js{Class}PrototypeFunction_{method}",
]
```

This command takes a .toml file and adds label frames to a profile based on matching function names. We want to use this for profiles from samply, to insert labels for DOM calls and Layout / Style / etc. Example: Before: https://share.firefox.dev/48wEADM After: https://share.firefox.dev/3P9d3BQ The toml file has to be provided by the user, because the matched function names are specific to the program being profiled. Here's an example toml file: https://gist.github.com/mstange/827c40404c987bc566b8b324efc0a04f

Based on #6076.
This lets us create profiles like https://share.firefox.dev/4mPPTgr with DOM label frames that show up in the JS-only view, for profiles from samply, based on function name matching. The matchers are declared in a toml file that is passed to the script.
Example TOML file: https://gist.github.com/mstange/827c40404c987bc566b8b324efc0a04f
