On CloudABI we should append the timezone name to the end of the locale
(e.g., nl_NL.UTF-8@Europe/Amsterdam). By fixing the locale names we can
already let a lot of locale related tests pass.

1. Move relocation addendum reading code to the MipsRelocationHandler
class to reduce code duplication.
2. Factor out the relocations calculation code into the separate
function to be ready to handle MIPS N64 ABI relocation chains.
No functional changes.
llvm-svn: 231641
We should not take in account a type of "source" symbol. Cross mode jump
adjustment is requred when target symbol and relocation belong to
different (regular/microMIPS) instruction sets.

Thic change have effect wehn the AVX registers aren't available with
reporting the count of user registers without them.

Fixing this also exposed a related issue where the landingpad under construction was not
cleaned up when an error was raised, which would cause bad reference errors before the
error could actually be printed.

For inner one of nested loops, it is more likely to be a hot loop,
and the runtime check can be promoted out from patch 0001, so the
overhead is less, we can try a doubled threshold to unroll more loops.
llvm-svn: 231632
Runtime unrolling is an expensive optimization which can bring benefit
only if the loop is hot and iteration number is relatively large enough.
For some loops, we know they are not worth to be runtime unrolled.
The scalar loop from vectorization is one of the cases.
llvm-svn: 231631
Runtime unrollng will introduce a runtime check in loop prologue.
If the unrolled loop is a inner loop, then the proglogue will be inside
the outer loop. LICM pass can help to promote the runtime check out if
the checked value is loop invariant.

This only warns on direct gotos and indirect gotos with a unique label
(`goto *&&label;`). Jumping out ith a true indirect goto is already an error.
This isn't O(1), but goto statements are less common than continue, break, and
return. Also, the GetDeepestCommonScope() call in the same function does the
same amount of work, so this isn't worse than what's there in a complexity
sense, and it should be pretty fast in practice.
This is the last piece that was missing in r231623.

Summary:
See the two test cases.
; Can fold fcmp with undef on one side by choosing NaN for the undef
; Can fold fcmp with undef on both side
; fcmp u_pred undef, undef -> true
; fcmp o_pred undef, undef -> false
; because whatever you choose for the first undef
; you can choose NaN for the other undef

ParseCompoundStatement() currently never returns StmtError, but if it did,
Sema would keep the __finally scope on its stack indefinitely. Explicitly
add an error callback that clears it.
llvm-svn: 231625
Since continue, break, return are much more common than __finally, this tries
to keep the work for continue, break, return O(1). Sema keeps a stack of active
__finally scopes (to do this, ActOnSEHFinally() is split into
ActOnStartSEHFinally() and ActOnFinishSEHFinally()), and the various jump
statements then check if the current __finally scope (if present) is deeper
than then destination scope of the jump.
The same warning for goto statements is still missing.
This is the moral equivalent of MSVC's C4532.

Previously, getEmptyKey and getTombstoneKey return the same value
in the sense of isEqual defined by the same class, although they
need to be distinct values. This could confuse DenseMap.
We didn't see any issue by this wrong code because we don't delete
elements from the symbol table. We only add or replace elements.
But this is a bug and needs to be fixed anyway.

All readers except PE/COFF reader create layout-after edges to preserve
the original symbol order. PE/COFF uses layout-before edges as primary
edges for no reason.
This patch makes PE/COFF reader to create layout-after edges.
Resolver is updated to recognize reverse edges of layout-after edges
in the garbage collection pass.
Now we can retire layout-before edges. I don't do that in this patch
because if I do, I would have updated many tests to replace all
occurrrences of "layout-before" with "layout-after". So that's a TODO.
