[MC] Fix handling of end-of-line preprocessor comments

Summary:
When parsing assembly where the line comment syntax is not hash, the
lexer cannot distinguish between hash's that start a hash line comment
and one that is part of an assembly statement and must be distinguished
during parsing. Previously, this was incompletely handled by not checking
for EndOfStatement at the end of statements and interpreting hash
prefixed statements as comments.

Change EndOfStatement Parsing to check for Hash comments and reintroduce
Hash statement parsing to catch previously handled cases.

CCACHE_SIZE is important in the perspective of buildbot to increase the

the data source we were using for determining modref behaviors
explicitly ignores operations on non-pointer values. So, it wouldn't
note e.g. storing an i32 to an i32* (or loading an i64 from an i64*).
It also ignores external function calls, rather than acting
conservatively for them.

(N.B. These operations, where necessary, *are* tracked by CFLAA; we just

imprecise, so it's unlikely that we can provide reasonably good modref

[AArch64] Return the correct size for TLSDESC_CALLSEQ

The branch relaxation pass is computing the wrong offsets because it assumes
TLSDESC_CALLSEQ eats up 4 bytes, when in fact it is lowered to an instruction
sequence taking up 16 bytes. This can become a problem in huge files with lots
of TLS accesses, as it may slowly move branch targets out of the range computed
by the branch relaxation pass.

[SimplifyCFG] Range reduce switches

If a switch is sparse and all the cases (once sorted) are in arithmetic progression, we can extract the common factor out of the switch and create a dense switch. For example:

    switch (i) {
    case 5: ...
    case 9: ...
    case 13: ...
    case 17: ...
    }

can become:

    if ( (i - 5) % 4 ) goto default;
    switch ((i - 5) / 4) {
    case 0: ...
    case 1: ...
    case 2: ...
    case 3: ...
    }

or even better:

   switch ( ROTR(i - 5, 2) {
   case 0: ...
   case 1: ...
   case 2: ...
   case 3: ...
   }

The division and remainder operations could be costly so we only do this if the factor is a power of two, and emit a right-rotate instead of a divide/remainder sequence. Dense switches can be lowered significantly better than sparse switches and can even be transformed into lookup tables.

When extracting a set of blocks make sure to inherit all of the target
dependent attributes to make sure that the function will be valid for
lowering. One example is the "target-features" attribute for x86, if the
extracted region has functionality that relies on a specific feature it
will fail to be lowered.
This also allows for extracted functions to be valid for inlining, at

Summary:
This change fixes issues with `LLVM_CONSTEXPR` functions and
`TrailingObjects::FixedSizeStorage`. In particular, some of the
functions marked `LLVM_CONSTEXPR` used by `FixedSizeStorage` were not
implemented such that they evaluate successfully as part of a constant
expression despite constant arguments.

This change also implements a more traditional template-meta path to
accommodate MSVC, and adds unit tests for `FixedSizeStorage`.

Drive-by fix: the access control for members of `TrailingObjectsImpl` is
tightened.

- the evaluation of the function, given constant arguments, will not
  fail during the evaluation of a constant expression, and
- the above properties are easily verifiable at a glance.

triggers a static assertion failure.
