Subject: [MS Demangler] Add a flag for dumping types without tag specifier.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ed72a6443a3697cc05138bf87688e8e4478e0fdb;p=llvm

[MS Demangler] Add a flag for dumping types without tag specifier.

Sometimes it's useful to be able to output demangled names without
tag specifiers like "struct", "class", etc.  This patch adds a
flag enabling this.
