Misclassification of PHP syntax tokens

Type: Bug

VSCode assigns the wrong TextMate scope to several built-in PHP functions. The following functions are classified as entity.name.function.php instead of their corresponding support.function scope.

hrtime(); //should be support.function.datetime.php
stream_context_set_options(); //should be support.function.streamsfuncs.php
mysqli_connect_error(); //should be support.function.mysqli.php
mysqli_connect_errno(); //should be support.function.mysqli.php
mysqli_affected_rows(); //should be support.function.mysqli.php
mysqli_stmt_error(); //should be support.function.mysqli.php
mysqli_error(); //should be support.function.mysqli.php
mysqli_errno(); //should be support.function.mysqli.php

The issue is that entity.name.function.php means that a function is user defined and might have a different color than support.function.* which is a built-in function. If we indeed use a different color and add similar built-in functions the issue becomes more apparent:

stream_context_set_params(); //correct
stream_context_get_params(); //correct
stream_context_set_options(); //incorrect
stream_context_get_options(); //correct

time(); //correct
microtime(); //correct
hrtime(); //incorrect
sleep(); //correct
usleep(); //correct

mysqli_report(); //correct
mysqli_connect(); //correct
mysqli_query(); //correct
mysqli_fetch_row(); //correct
mysqli_fetch_assoc(); //correct
mysqli_affected_rows(); //incorrect
mysqli_stmt_error(); //incorrect
mysqli_error(); //incorrect
mysqli_errno(); //incorrect
mysqli_stmt_close(); //correct
mysqli_close(); //correct

It seems possible that there are further built-in functions that are misclassified, these are merely the ones that I encountered.

Use the listed PHP functions and their expected support.function.* scopes as the starting cases; inspect the grammar rules that classify them and compare them with the neighboring correctly classified functions named in the report. Done when the listed functions no longer receive entity.name.function.php and scope checks confirm the expected built-in scopes.
