39ff10a293 use the MapEntryTy typedef instead of writing it out long form,
add some fixme's about methods that should be removed.

Merged from type-system-rewrite.

cf886188fb add option for literal formatting to APInt::toString()
toString() now takes an optional bool argument that,
depending on the radix, adds the appropriate prefix
to the integer's string representation that makes it into a
meaningful C literal, e.g.:

hexademical: '-f' becomes '-0xf'
octal: '77' becomes '077'
binary: '110' becomes '0b110'

74ee8ace0c Introduce PackedVector, useful for storing a vector of values using a specific number of bits for each
value. Both signed and unsigned types can be used, e.g

   PackedVector<signed, 2> vec;

will create a vector accepting values -2, -1, 0, 1. Any other value will hit an assertion.

832a9d1a76 On Darwin ARM, set the UNWIND_RESUME libcall to _Unwind_SjLj_Resume.
This is important for the correct lowering of unwind instructions
(which doesn't matter at all) and llvm.eh.resume calls (which does).

-memcmp should not be called with NULL (even if size is 0)

tends to look at the same interference data many times. The InterferenceCache
class caches queries for unaltered LiveIntervalUnions.

03ef449917 Reset StringMap's NumTombstones on clears and rehashes.
StringMap was not properly updating NumTombstones after a clear or rehash.

This was not fatal until now because the table was growing faster than
NumTombstones could, but with the previous change of preventing infinite
growth of the table the invariant (NumItems + NumTombstones <= NumBuckets)
stopped being observed, causing infinite loops in certain situations.

414fdbdb01 Prevent infinite growth of the DenseMap.
When the hash function uses object pointers all free entries eventually
become tombstones as they are used at least once, regardless of the size.

DenseMap cannot function with zero empty keys, so it double size to get
get ridof the tombstones.

However DenseMap never shrinks automatically unless it is cleared, so
the net result is that certain tables grow infinitely.

The solution is to make a fresh copy of the table without tombstones
instead of doubling size, by simply calling grow with the current size.

2746000f4f Add APFloat::getExactInverse.
The idea is, that if an ieee 754 float is divided by a power of two, we can
turn the division into a cheaper multiplication. This function sees if we can
get an exact multiplicative inverse for a divisor and returns it if possible.

This is the hard part of PR9587.

I tested many inputs against llvm-gcc's frotend implementation of this
optimization and didn't find any difference. However, floating point is the
land of weird edge cases, so any review would be appreciated.
