b96942f6ec YAML: Implement block scalar parsing.
This commit implements the parsing of YAML block scalars.
Some code existed for it before, but it couldn't parse block
scalars.

This commit adds a new yaml node type to represent the block
scalar values. 

This commit also deletes the 'spec-09-27' and 'spec-09-28' tests
as they are identical to the test file 'spec-09-26'.

This commit introduces 3 new utility functions to the YAML scanner
class: `skip_s_space`, `advanceWhile` and `consumeLineBreakIfPresent`.

1336daad86 Use std::bitset for SubtargetFeatures
Previously, subtarget features were a bitfield with the underlying type being uint64_t. 
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.

The first two times this was committed (r229831, r233055), it caused several buildbot failures. 
At least some of the ARM and MIPS ones were due to gcc/binutils issues, and should now be fixed.

aeda490976 Fix tablegen's PrintFatalError function to run registered file
cleanups.

Also, change code in tablegen which printed a message and then called
"exit(1)" to use PrintFatalError, instead.

This fixes instances where an empty output file was left behind after
a failed tablegen invocation, which would confuse subsequent ninja
runs into not attempting to rebuild.

fcae7eada1 Add polly support to sort_includes.py
Changes:
 -  Add "isl/" as a system library prefix. Even though isl is regularly
    imported into polly, it is still used like an external library.
 -  Add "json/" as a system library prefix. Polly uses json-cpp as external
    library.
 -  Distinguish between llvm and subproject libraries. Always sort subprojects
    before LLVM. This was already the case with clang, as 'clang' comes before
    'llvm', but we also want 'polly' to be sorted before 'llvm'.

The sorting of headers that are not part of Polly or isl remains unchanged.

This commit adds the missing yaml-bench utility to the
makefile in utils. It was missing before and it caused
the regression tests to fail on some buildbots when llvm-lit 
couldn't find yaml-bench when llvm was built without 
cmake after I committed r236754.

9e31c0cf91 YAML: Enable the YAMLParser tests.
This commit enables the tests located in test/YAMLParser directory.
Those tests were never actually enabled, as llvm-lit didn't pick up the
files with the 'data' extension. The commit renames those test files to files
with the 'test' extension so that llvm-lit would find them.

This commit also modifies yaml-bench so that it returns an error status
if an error occurred during parsing. It also adds the '-use-color'
command line option to yaml-bench (to make sure that file check matches
the error messages in the output stream).

This commit modifies some of the renamed tests so that they wouldn't
fail. It gets rid of XFAILs and uses the 'not' command instead for
some of the tests that have to fail during parsing. This commit
also adds some 'FIXME' comments to a couple of tests that are
supposed to fail but currently pass because of various bugs
in the implementation of the yaml parser.

1e3da044d8 Add support for v1i128 type.
The v1i128 type is needed for the quadword add/substract instructions introduced
in POWER8. Futhermore, the PowerPC ABI specifies that parameters of type v1i128
are to be passed in a single vector register, while parameters of type i128 are
passed in pairs of GPRs. Thus, it is necessary to be able to differentiate
between v1i128 and i128 in LLVM.

The '/' character in the test name of a type-parameterized test is not a

f09378397e [MCInstPrinter] Enable MCInstPrinter to change its behavior based on the
per-function subtarget.

Currently, code-gen passes the default or generic subtarget to the constructors
of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which
enables some targets (AArch64, ARM, and X86) to change their instprinter's
behavior based on the subtarget feature bits. Since the backend can now use
different subtargets for each function, instprinter has to be changed to use the
per-function subtarget rather than the default subtarget.

This patch takes the first step towards enabling instprinter to change its
behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to
AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the
various print methods table-gen auto-generates. 

I will follow up with changes to instprinters of AArch64, ARM, and X86.

3220d112fa [Tablegen] Attempt to add support for patterns containing nodes with multiple results.
This is needed for AVX512 masked scatter/gather support.

The R600 change is necessary to remove a hack that was working around the lack of multiple results.

5101c89f13 Do not track subregister liveness when it brings no benefits
Some subregisters are only to indicate different access sizes, while not
providing any way to actually divide the register up into multiple
disjunct parts. Avoid tracking subregister liveness in these cases as it
is not beneficial.

8b41add6ca TableGen: Fix register class lane masks being too conservative.
When calculating the lanemask of a register class we have to include the
masks of subregisters supported by any of the class members, not just
the ones supported by all class members.

This fixes problems when coalescing towards a subclass with additional
subregisters available.

The attached testcase works fine as is, but does crash if you enable
subregister liveness on x86 without this change applied.

703b185464 Remove many superfluous SmallString::str() calls.
Now that SmallString is a first-class citizen, most SmallString::str()
calls are not required. This patch removes a whole bunch of them, yet
there are lots more.

There are two use cases where str() is really needed:
1) To use one of StringRef member functions which is not available in
SmallString.
2) To convert to std::string, as StringRef implicitly converts while 
SmallString do not. We may wish to change this, but it may introduce
ambiguity.
