[WebAssembly] Add first claass symbol table to wasm objects

This is combination of two patches by Nicholas Wilson:
  1. https://reviews.llvm.org/D41954
  2. https://reviews.llvm.org/D42495

Along with a few local modifications:
- One change I made was to add the UNDEFINED bit to the binary format
  to avoid the extra byte used when writing data symbols.  Although this
  bit is redundant for other symbols types (i.e. undefined can be
  implied if a function or global is a wasm import)
- I prefer to be explicit and consistent and not have derived flags.
- Some field renaming.
- Some reverting of unrelated minor changes.
- No test output differences.

Make undefined symbol in DSO to pull out object files from archive files.

We have an internal program that does't link without this patch. I don't

the GNU linkers' behavior that they pull out object files from archive
files to resolve undefined symbols in DSOs. We already allow that kind of

symbols, in particular, for "__progname" symbol (which is usually in
crt0.o), but that doesn't work if the symbol is in an archive file.

[AlignmentFromAssumptions] Set source and dest alignments of memory intrinsiscs separately

Summary:
This change is part of step five in the series of changes to remove alignment argument from
memcpy/memmove/memset in favour of alignment attributes. In particular, this changes the
AlignmentFromAssumptions pass to cease using the old getAlignment()/setAlignment API of
MemoryIntrinsic in favour of getting/setting source & dest specific alignments through
the new API. This allows us to simplify some of the code in this pass and also be more
aggressive about setting the source and destination alignments separately.

Steps:
Step 1) Remove alignment parameter and create alignment parameter attributes for
memcpy/memmove/memset. ( rL322965, rC322964, rL322963 )
Step 2) Expand the IRBuilder API to allow creation of memcpy/memmove with differing
source and dest alignments. ( rL323597 )
Step 3) Update Clang to use the new IRBuilder API. ( rC323617 )
Step 4) Update Polly to use the new IRBuilder API. ( rL323618 )
Step 5) Update LLVM passes that create memcpy/memmove calls to use the new IRBuilder API,
and those that use use MemIntrinsicInst::[get|set]Alignment() to use [get|set]DestAlignment()
and [get|set]SourceAlignment() instead. ( rL323886, rL323891, rL324148, rL324273, rL324278,
rL324384, rL324395, rL324402, rL324626, rL324642, rL324653, rL324654, rL324773, rL324774,
rL324781, rL324784, rL324955, rL324960 )
Step 6) Remove the single-alignment IRBuilder API for memcpy/memmove, and the
MemIntrinsicInst::[get|set]Alignment() methods.

6 years ago[clangd] Not collect include headers for dynamic index for now.
Eric Liu [Thu, 22 Feb 2018 10:14:05 +0000 (10:14 +0000)]
[clangd] Not collect include headers for dynamic index for now.

Summary:
The new behaviors introduced by this patch:
o When include collection is enabled, we always set IncludeHeader field in Symbol
even if it's the same as FileURI in decl.
o Disable include collection in FileIndex which is currently only used to build
dynamic index. We should revisit when we actually want to use FileIndex to global
index.
o Code-completion only uses IncludeHeader to insert headers but not FileURI in
CanonicalDeclaration. This ensures that inserted headers are always canonicalized.
Note that include insertion can still be triggered for symbols that are already
included if they are merged from dynamic index and static index, but we would
only use includes that are already canonicalized (e.g. from static index).

Reason for change:
Collecting header includes in dynamic index enables inserting includes for headers
that are not indexed but opened in the editor. Comparing to inserting includes for
symbols in global/static index, this is nice-to-have but would probably require
non-trivial amount of work to get right. For example:
o Currently it's not easy to fully support CanonicalIncludes in dynamic index, given the way
we run dynamic index.
o It's also harder to reason about the correctness of include canonicalization for dynamic index
(i.e. symbols in the current file/TU) than static index where symbols are collected
offline and sanity check is possible before shipping to production.
o We have less control/flexibility over symbol info in the dynamic index
(e.g. URIs, path normalization), which could be used to help make decision when inserting includes.

As header collection (especially canonicalization) is relatively new, and enabling
it for dynamic index would immediately affect current users with only dynamic
index support, I propose we disable it for dynamic index for now to avoid
compromising other hot features like code completion and only support it for
static index where include insertion would likely to bring more value.

[dsymutil] Be smarter in caching calls to realpath

Calling realpath is expensive but necessary to perform the uniqueing in
dsymutil. Although we already cached the results for every individual
file in the line table, we had reports of it taking 40 seconds of a 3.5
minute link.

This patch adds a second level of caching. When we do have to call
realpath, we cache its result for its parents path. We didn't replace
the existing caching, because it's fast (indexed) and saves us from
reading the line table for entries we've already seen.

For WebkitCore this results in a decrease of 11% in linking time: from
85.79 to 76.11 seconds (average over 3 runs).
