While fuzzing LLVM bitcode files, I discovered that (1) the bitcode reader doesn't check that alignments are no larger than 2**29; (2) downstream code doesn't check the range; and (3) for values out of range, corresponding large memory requests (based on alignment size) will fail. This code fixes the bitcode reader to check for valid alignments, fixing this problem.

[libc++] Try and prevent evaluation of `is_default_constructible` on tuples default constructor if it is not needed.
Summary:
Currently parts of the SFINAE on tuples default constructor always gets evaluated even when the default constructor is never called or instantiated. This can cause a hard compile error when a tuple is created with types that do not have a default constructor. Below is a self contained example using a pair like class. This code will not compile but probably should.
```
#include <type_traits>
template <class T>
struct IllFormedDefaultImp {
IllFormedDefaultImp(T x) : value(x) {}
constexpr IllFormedDefaultImp() {}
T value;
};
typedef IllFormedDefaultImp<int &> IllFormedDefault;
template <class T, class U>
struct pair
{
template <bool Dummy = true,
class = typename std::enable_if<
std::is_default_constructible<T>::value
&& std::is_default_constructible<U>::value
&& Dummy>::type
>
constexpr pair() : first(), second() {}
pair(T const & t, U const & u) : first(t), second(u) {}
T first;
U second;
};
int main()
{
int x = 1;
IllFormedDefault v(x);
pair<IllFormedDefault, IllFormedDefault> p(v, v);
}
```
One way to fix this is to use `Dummy` in a more involved way in the constructor SFINAE. The following patch fixes these sorts of hard compile errors for tuple.

AsmParser/Writer: Handle symbolic constants in DI 'flags:'
Parse (and write) symbolic constants in debug info `flags:` fields.
This prevents a readability (and CHECK-ability) regression with the new
debug info hierarchy.
Old (well, current) assembly, with pretty-printing:
!{!"...\\0016387", ...} ; ... [public] [rvalue reference]
Flags field without this change:
!MDDerivedType(flags: 16387, ...)
Flags field with this change:
!MDDerivedType(flags: DIFlagPublic | DIFlagRValueReference, ...)
As discussed in the review thread, this isn't a final state. Most of
these flags correspond to `DW_AT_` symbolic constants, and we might
eventually want to support arbitrary attributes in some form. However,
as it stands now, some of the flags correspond to other concepts (like
`FlagStaticMember`); until things are refactored this is the simplest
way to move forward without regressing assembly.

[PlaceSafepoints] Adjust enablement logic to default to off and be GC configurable per GC
Previously, this pass ran over every function in the Module if added to the pass order. With this change, it runs only over those with a GC attribute where the GC explicitly opts in. A GC can also choose which of entry safepoint polls, backedge safepoint polls, and call safepoints it wants. I hope to get these exposed as checks on the GCStrategy at some point, but for now, the checks are manual string comparisons.

AsmParser: Use do{}while(false) in macros, NFC
`do { ... } while (false)` is standard macro etiquette for forcing
instantiations into a single statement and requiring a `;` afterwards,
making statement-like macros easier to reason about (and harder to use
incorrectly).
I'm about to modify the macros in `LexIdentifier()`. I noticed that the
`KEYWORD` macro *does* follow the rule, so I thought I'd clean up the
other macros to match (otherwise might not be worth changing, since the
benefits of this pattern are fairly irrelevant here).

LiveRangeCalc: Don't start liveranges of PHI instruction at the block begin.
Summary:
Letting them begin at the PHI instruction slightly simplifies the code
but more importantly avoids breaking the assumption that live ranges
starting at the block begin are also live at the end of the predecessor
blocks. The MachineVerifier checks that but was apparently never run in
the few instances where liveranges are calculated for machine-SSA
functions.
