[AST] Fix handling of long double and bool in __builtin_bit_cast

On x86, long double has 6 unused trailing bytes. This patch changes the
constant evaluator to treat them as though they were padding bytes, so reading
from them results in an indeterminate value, and nothing is written for them.
Also, fix a similar bug with bool, but instead of treating the unused bits as
padding, enforce that they're zero.

Store an Identifier instead of a StringRef for the OperationName inside an AbstractOperation (NFC)

Instead of storing a StringRef, we keep an Identifier which otherwise requires a lock on the context to retrieve.
This will allow to get an Identifier for any registered Operation for "free".

[PowerPC] Implemented Vector Multiply Builtins

This patch implements the builtins for Vector Multiply Builtins (vmulxxd family of instructions), and adds the appropriate test cases for these builtins. The builtins utilize the vector multiply instructions itnroduced with ISA 3.1.

The `__attribute__((destructor(100)))` diagnostic does not have a
warning option in GCC 8 (before r264853) and thus cannot be suppressed.

This patch restores the default traversal for Transformer's `makeRule` to
`TK_AsIs`. The implicit mode has proven problematic.

[lldb/test] Fix TestPlatform*.py Windows failures (NFC)

This patch fixes the windows failures introduced by `addb514`:

This macro, used in the test to check the platform, was missing a `_`,
making the test behave like it was run from a UNIX platform.
