[DebugInfo][DWARF5]: Added support for debuginfo generation for defaulted parameters This patch adds support for dwarf emission/dumping part of debuginfo generation for defaulted parameters.

// Test for DebugInfo for Defaulted parameters for C++ templates
// Supported: -O0, standalone DI

// CHECK: DILocalVariable(name: "f1", {{.*}}, type: ![[TEMPLATE_TYPE:[0-9]+]]
// CHECK: [[TEMPLATE_TYPE]] = {{.*}}!DICompositeType({{.*}}, templateParams: ![[F1_TYPE:[0-9]+]]
DebugInfo: Fix default template parameter computation for dependent non-type template parameters This addresses the immediate bug, though in theory we could still produce a default parameter for the DWARF in this test case - but other cases will be definitely unachievable (you could have a default parameter that cannot be evaluated - so long as the user overrode it with another value rather than relying on that default)

// CHECK: [[FIRST]] = !DITemplateTypeParameter(name: "T", type: !{{[0-9]*}})
// CHECK: [[SECOND]] = !DITemplateValueParameter(name: "i", type: !{{[0-9]*}}, value: i32 6)
DebugInfo: Defaulted non-type template parameters of bool type Caused an assertion due to mismatched bit widths - this seems like the right API to use for a possibly width-varying equality test. Though certainly open to some post-commit review feedback if there's a more suitable way to do this comparison/test.
