[NodeAnalyzer] Treat trailing comment and infinite loop as terminating in last block stmts

[TomasVotruba]

Fixes the ConsoleExecuteReturnIntRector false positive reported in rectorphp/rector#9897.

TerminatedNodeAnalyzer::isTerminatedInLastStmts() only accepted a Return_ or an exit/throw expression as the last statement of a block. Two cases slipped through and made a fully-terminated try/catch look like it falls through:

• a trailing comment at the end of a block is parsed as a Nop stmt, hiding the real last return
• a while (true) / do/for infinite loop with no break at the end of a block never falls through, but was not recognized

Both now report the block as terminated, so no unreachable return/statement is appended after such a try/catch.

Covered with two RemoveUnreachableStatementRector fixtures (comment in catch, infinite while in try).
