Parse PDB Name Hash Table

PDB has a lot of similar data structures.  We already have code
for parsing a Name Map, but PDB seems to have a different but
very similar structure that is a hash table.  This is the
beginning of code needed in order to parse the name hash table,
but it is not yet complete.  It parses the basic metadata of
the hash table, the bucket array, and the names buffer, but
doesn't use any of these fields yet as the data structure
requires a non-trivial amount of work to understand.

Marcin Koscielnicki [Sat, 30 Apr 2016 09:57:34 +0000 (09:57 +0000)]
[ASan] Add shadow offset for SystemZ.

SystemZ on Linux currently has 53-bit address space.  In theory, the hardware
could support a full 64-bit address space, but that's not supported due to
kernel limitations (it'd require 5-level page tables), and there are no plans
for that.  The default process layout stays within first 4TB of address space
(to avoid creating 4-level page tables), so any offset >= (1 << 42) is fine.
Let's use 1 << 52 here, ie. exactly half the address space.

I've originally used 7 << 50 (uses top 1/8th of the address space), but ASan
runtime assumes there's some space after the shadow area.  While this is
fixable, it's simpler to avoid the issue entirely.

Also, I've originally wanted to have the shadow aligned to 1/8th the address
space, so that we can use OR like X86 to assemble the offset.  I no longer
think it's a good idea, since using ADD enables us to load the constant just
once and use it with register + register indexed addressing.

Mark guards on true as "trivially dead"

This moves some logic added to EarlyCSE in rL268120 into
`llvm::isInstructionTriviallyDead`.  Adds a test case for DCE to
demonstrate that passes other than EarlyCSE can now pick up on the new
information.

[EarlyCSE] Simplify guard intrinsics

Summary:
This change teaches EarlyCSE some basic properties of guard intrinsics:

 - Guard intrinsics read all memory, but don't write to any memory
 - After a guard has executed, the condition it was guarding on can be
   assumed to be true
 - Guard intrinsics on a constant `true` are no-ops
