Rafael Espindola e37b939793 Add test for PR10068.

Argyrios Kyrtzidis 92dd466a1a [PCH] Store the offsets of source location file entries and go through them 
in ASTReader::validateFileEntries().

This avoids going through all source location entries and fixes the performance regression.
Many thanks to Doug for the hint!

Howard Hinnant 9eebe11dd5 I've become quite disatsified with the lack of noexcept specifications on container move construction, move assignment operator and swap. Without proper decoration on at least move construction, vectors of containers will have unacceptable performance. Here's the fix for deque.

Jim Grosbach dac0238ed2 .cfi directive register parsing flexibility. 
Parsing a register name/number for .cfi directives can't assume that a
register name starts with a '%' token. Be more flexible and check for a
register number instead. Still unlikely to be perfect, but it allows us
to parse both plain identifiers as register names and integers as register
numbers, which is what we're wanting to support at this point.

Jakob Stoklund Olesen c58894bc36 Add a RegisterClassInfo class that lazily caches information about 
register classes.

It provides information for each register class that cannot be
determined statically, like:

- The number of allocatable registers in a class after filtering out the
  reserved and invalid registers.

- The preferred allocation order with registers that overlap callee-saved
  registers last.

- The last callee-saved register that overlaps a given physical register.

This information usually doesn't change between functions, so it is
reused for compiling multiple functions when possible.  The many
possible combinations of reserved and callee saves registers makes it
unfeasible to compute this information statically in TableGen.

Use RegisterClassInfo to count available registers in various heuristics
in SimpleRegisterCoalescing, making the pass run 4% faster.

Eli Friedman b576b1675c When marking a block as being unanalyzable, use "Clobber" on the terminator instead of the first instruction in the block. This is a bit of a hack; "Clobber" isn't really the right marking in the first place. memdep doesn't really have any way of properly expressing "unanalyzable" at the moment. Using it on the terminator is much less ambiguous than using it on an arbitrary instruction, though. 
In the given testcase, the "Clobber" was pointing to a load, and GVN was incorrectly assuming that meant that the "Clobber" load overlapped the load being analyzed (when they are actually unrelated).

The included testcase tests both this commit and r132434.

Part two of rdar://9429882.  (r132434 was mislabeled.)

Eli Friedman 4b6eeb9ca2 In MemoryDependenceAnalysis::getNonLocalPointerDepFromBB, if a given block is is deemed unanalyzable (and we execute one of the "goto PredTranslationFailure" statements), make sure we don't put information about the predecessors of that block into the returned data structures; this can lead to, among other things, extraneous results (which will confuse passes using memdep). Fixes an assert in GVN compiling ruby. Part of rdar://problem/9521954 .
