When the base register (register pointing to the jump table) is the PC, we expect the jump table to directly follow the jump sequence with no intervening padding.

If there is intervening padding, the calculated offsets will not be correct. One solution would be to account for any padding in the emitted LDRB instruction, but at the moment we don't support emitting MCExprs for the load offset.

In the meantime, it's correct and only a slight amount worse to just move the padding up, from just before the jump table to just before the jump instruction sequence. We can do that by emitting code alignment before the jump sequence, as we know the number of instructions in the sequence is always 4.

This renames the functionalities/postmortem/linux-core to elf-core and puts the
"linux" part into the individual names of the core files. Since the tests for
linux and freebsd core files are going to be very similar, having them close
together means they can reuse most of the plumbing.

In these tests there are some paths that explicitly throw, so use
the TEST_THROW macro that was proposed for this and then skip the tests
that may enter the throwing path.

[AVX-512][Sema] Add more intrinsics to the checks for valid immediates for embedded rounding control arguments.

llvm-svn: 286097

Summary:
The current version does not deduplicate equivalent file paths correctly.
For example, a relative path and an absolute path are considered inequivalent.
Comparing FileEnry addresses these issues.

We shouldn't access past the end of an array, even if we think that the
layout of the struct containing the array is always what we expect. The
compiler is free to optimize away the stores as undefined behavior, and
in fact, GCC 6.2.1 claims it will do exactly this.

[AVX-512] Remove masked pmovzx/pmovsx builtins and autoupgrade them to selects and native zext/sext.

This mostly reuses earlier autoupgrade support for the sse and avx equivalents. Just needed to add the code to add the select.

I will probably submit a lot of small trivial changes
like this over the coming weeks.  The end goal is to
convert Options::SetOptionValue to take the option arg
as a StringRef, but doing so in one pass would be a huge
mess of disparate changes just to satisfy the compiler,
and with a high risk of breaking.  So I'm going to do
this in small pieces, changing seemingly random things
here and there until the final change to the signature
of Options::SetOptionValue() can be done trivially.

This handles the last case of the builtin function calls that we would
generate code which differed from Microsoft's ABI.  Rather than
generating a call to `__pow{d,s}i2` we now promote the parameter to a
float or double and invoke `powf` or `pow` instead.

The clr/set/toggle-bit instructions (with the bit index given as an
immediate operand) had both, custom selection code that generated them,
and selection patterns at the same time. The selection patterns were
not used, because the custom selection code was executed first.
This patch removes the custom code in favor of the selection patterns.
The custom code handled 64-bit registers as well with an immediate bit
index, and so new patterns were added to implement that.

It was also the same case for the instruction "Rd += asr(Rs, Rt)",
except that the custom code did not offer any additional functionality,
and was simply removed.
