Summary:
noload_lookups() was too lazy: in addition to avoiding external decls, it
avoided populating the lazy lookup structure for internal decls.
This is the right behavior for the existing callsite in ASTDumper, but I think
it's not a very useful default, so we populate it by default.
While here:
- remove an unused test file accidentally added in r322371.
- remove lookups_begin()/lookups_end() in favor of lookups().begin(), which is
more common and more efficient.

Summary:
Introduce clang_getCursorPrettyPrinted() for pretty printing
declarations. Expose also PrintingPolicy, so the user gets more
fine-grained control of the entities being printed.
The already existing clang_getCursorDisplayName() is pretty limited -
for example, it does not handle return types, parameter names or default
arguments for function declarations. Addressing these issues in
clang_getCursorDisplayName() would mean to duplicate existing code
(e.g. clang::DeclPrinter), so rather expose new API to access the
existing functionality.

We were trying to emit a diag::err_bad_multiversion_option diagnostic,
which expects an int as its first argument, with a string argument. As
it happens, the string `Feature` that was causing this was shadowing an
int `Feature` from the surrounding scope. :)

Summary:
There are only two valid integrated Clang driver tools: `-cc1` and
`-cc1as`. If a user asks for an unknown tool, such as `-cc1asphalt`,
an error message is displayed to indicate that there is no such tool,
but the message doesn't indicate what the valid options are.
Include the valid options in the error message.

Thanks to Eli Friedman, who suggested the reason these tests failed on a few
buildbots yet works fine locally is because non-assert builds don't emit value

The skipped preprocessor ranges are now serialized in the AST PCH file. This fixes, for example, libclang's clang_getSkippedRanges() returning zero ranges after reparsing a translation unit.

RISCVABIInfo is implemented in terms of XLen, supporting both RV32 and RV64.
Unfortunately we need to count argument registers in the frontend in order to
determine when to emit signext and zeroext attributes. Integer scalars are
extended according to their type up to 32-bits and then sign-extended to XLen
when passed in registers, but are anyext when passed on the stack. This patch
only implements the base integer (soft float) ABIs.
For more information on the RISC-V ABI, see [the ABI
doc](https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md),
my [golden model](https://github.com/lowRISC/riscv-calling-conv-model), and

patch](https://reviews.llvm.org/D39898#2d1595b4) (specifically the comment
documenting frontend expectations).

Summary:
kunpck intrinsics were removed in favor of native IR a few months ago. The implementation lowers them as by operation on the integer types passed to the intrinsic and then just shifting, masking, and oring them together. A special X86 DAG combine was added to recognize this patter and turn it into a concat_vector operation.
I think it makes more sense to keep the IR implementation closer to vector operations on vXi1. Given that we expect these builtins to be used around other builtins that operate on k-registers which we try to represent in IR with vXi1. InstCombine should be able to get rid of the bitcasts between integers and vXi1 leaving only the vector operations.

Summary:
Use monospace for option flags in the PCH section, instead of the
italics that were being used previously.
I believe these used to be links, for which single backticks would
have been appropriate, but since they were un-link-ified in
https://reviews.llvm.org/rL275560, I believe monospace is now more
appropriate, and so two backticks are needed.
Test Plan:
Build the `docs-clang-html` target and confirm the options are rendered
using monospace font.

In https://reviews.llvm.org/D41733, the driver was modified such that,
when a user provided a mispelled option such as `-hel`, it would
suggest a valid option with a nearby edit distance: "did you mean
'-help'?".
Add these suggestions to invocations of `clang -cc1as` as well.

In the security package, we have a simple syntactic check that warns about
strcpy() being insecure, due to potential buffer overflows.
Suppress that check's warning in the trivial situation when the source is an

As @rjmccall suggested in D40023, we can get rid of
ABIInfo::shouldSignExtUnsignedType (used to handle cases like the Mips calling
convention where 32-bit integers are always sign extended regardless of the
sign of the type) by adding a SignExt field to ABIArgInfo. In the common case,
this new field is set automatically by ABIArgInfo::getExtend based on the sign
of the type. For targets that want greater control, they can use
ABIArgInfo::getSignExtend or ABIArgInfo::getZeroExtend when necessary. This
change also cleans up logic in CGCall.cpp.
There is no functional change intended in this patch, and all tests pass
unchanged. As noted in D40023, Mips might want to sign-extend unsigned 32-bit
integer return types. A future patch might modify
MipsABIInfo::classifyReturnType to use MipsABIInfo::extendType.
