Rui Ueyama 52a1509ea7 ELF2: LinkerScript: Interpret -l and = file name prefixes.
In the linker script, -l and = have the same meaning as in the command line.
In addition to that, if a path is not absolute, the path needs to be searched
from the search paths. This patch implements them.

Rui Ueyama b973256683 ELF2: Manage BumpPtrAllocator ownership better.
Previously, each ArgParser owned a BumpPtrAllocator, and arguments parsed
by an ArgParser would refer strings allocated using the BumpPtrAllocator
only when response files were used. This could cause a subtle bug because
such ownership was not obvious.

This patch moves the ownership from ArgParser to Driver and make the
ownership explicit.

Rui Ueyama 69960baad5 ELF2: Write .interp section on the first page in the exectuable.
Previously, we reserved the first page for the program header, so no
sections would be written to very beginning of the output file.
FreeBSD requires .interp section be exist on the first page, so that
was not good.

This patch calculates the size of the program header and then assign
addresses to the sections. Now the first section is located next to
the program header. Because the first section is .interp, it's very
likely to be on the first page.

Saleem Abdulrasool 911cfc11c4 builtins: spell inline as __inline
__inline is a vendor specific spelling for inline.  clang and gcc treat it the
same as inline, and is available in MSVC 2013 which does not implement C99
(VS2015 supports the inline keyword though).  This will allow us to build the
builtins using MSVC.

Teresa Johnson 1493ad9c24 Fix PR25101 - Handle anonymous functions without VST entries
Summary:
The change to use the VST function entries for lazy deserialization did
not handle the case of anonymous functions without aliases. In that case
we must fall back to scanning the function blocks as there is no VST
entry.

Keno Fischer 2cd66e9270 [RuntimeDyld] Fix performance problem in resolveRelocations with many sections
Summary:
Rather than just iterating over all sections and checking whether we have relocations for them, iterate over the relocation map instead. This showed up heavily in an artificial julia benchmark that does lots of compilation. On that particular benchmark, this patch gives
~15% performance improvements. As far as I can tell the primary reason why the original
loop was so expensive is that Relocations[i] actually constructs a relocationList (allocating memory & doing lots of other unnecessary computing) if none is found.

Duncan P. N. Exon Smith 5a82c916b0 Analysis: Remove implicit ilist iterator conversions
Remove implicit ilist iterator conversions from LLVMAnalysis.

I came across something really scary in `llvm::isKnownNotFullPoison()`
which relied on `Instruction::getNextNode()` being completely broken
(not surprising, but scary nevertheless).  This function is documented
(and coded to) return `nullptr` when it gets to the sentinel, but with
an `ilist_half_node` as a sentinel, the sentinel check looks into some
other memory and we don't recognize we've hit the end.

Rooting out these scary cases is the reason I'm removing the implicit
conversions before doing anything else with `ilist`; I'm not at all
surprised that clients rely on badness.

I found another scary case -- this time, not relying on badness, just
bad (but I guess getting lucky so far) -- in
`ObjectSizeOffsetEvaluator::compute_()`.  Here, we save out the
insertion point, do some things, and then restore it.  Previously, we
let the iterator auto-convert to `Instruction*`, and then set it back
using the `Instruction*` version:

    Instruction *PrevInsertPoint = Builder.GetInsertPoint();

    /* Logic that may change insert point */

    if (PrevInsertPoint)
      Builder.SetInsertPoint(PrevInsertPoint);

The check for `PrevInsertPoint` doesn't protect correctly against bad
accesses.  If the insertion point has been set to the end of a basic
block (i.e., `SetInsertPoint(SomeBB)`), then `GetInsertPoint()` returns
an iterator pointing at the list sentinel.  The version of
`SetInsertPoint()` that's getting called will then call
`PrevInsertPoint->getParent()`, which explodes horribly.  The only
reason this hasn't blown up is that it's fairly unlikely the builder is
adding to the end of the block; usually, we're adding instructions
somewhere before the terminator.
