Joel E. Denny 7663136ac6 [FileCheck] Extend -dump-input with substitutions ... Substitutions are already reported in the diagnostics appearing before the input dump in the case of failed directives, and they're reported in traces (produced by `-vv -dump-input=never`) in the case of successful directives. However, those reports are not always convenient to view while investigating the input dump, so this patch adds the substitution report to the input dump too. For example: ``` $ cat check CHECK: hello [[WHAT:[a-z]+]] CHECK: [[VERB]] [[WHAT]] $ FileCheck -vv -DVERB=goodbye check < input |& tail -8 <<<<<< 1: hello world check:1 ^~~~~~~~~~~ 2: goodbye word check:2'0 X~~~~~~~~~~~ error: no match found check:2'1 with "VERB" equal to "goodbye" check:2'2 with "WHAT" equal to "world" >>>>>> ``` Without this patch, the location reported for a substitution for a directive match is the directive's full match range. This location is misleading as it implies the substitution itself matches that range. This patch changes the reported location to just the match range start to suggest the substitution is known at the start of the match. (As in the above example, input dumps don't mark any range for substitutions. The location info in that case simply identifies the right line for the annotation.)
