lit is not very clever when it performs substitution on RUN lines. It
simply looks for a match anywhere in the line (without tokenization)
and replaces it by the expansion. This means that a RUN line containing
e.g. `-verify-ignore-unexpected=note` wouod be expanded to
`-verify-ignore-unexpected=<substitution for not>e`, which is
surprising and nonsensical.
It also means that something like `%compile_module` could be expanded
to `<substitution-for-%compile>_module` or to the correct substitution,
depending on the order in which substitutions are evaluated by lit.
To avoid such problems, it is a good habit to delimit custom substitutions
with some token. This commit does that for all substitutions used in the
libc++ and libc++abi test suites.
Summary:
The gdb pretty printer misprints variables declared via
using declarations of the form:
namespace foo {
using string_view = std::string_view;
string_view bar;
}
This change fixes that, by deferring the decision to ignore
types not inside std until after desugaring.

Summary:
This patch is an exact duplicate of https://reviews.llvm.org/D65609, except
that it uses the newly introduced testing framework to detect if gdb is present
so that the tests won't fail on machines without gdb.
