Subject: Improve MSVC visualizers for DeclSpec and TemplateName
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ddf46acf26445399aea795b3ea02e8d1c09fed37;p=clang

Improve MSVC visualizers for DeclSpec and TemplateName

DeclSpec now shows the TypeRep, ExprRep, or DeclRep as appropriate
TemplateName decodes and displays the StorageType
A few minor refinements to other types
