d4d1f85aa7 Tweak MemoryBuffer to allocate the class itself, the name and possibly the 
buffer in the same chunk of memory.

2 less mallocs for every uninitialized MemoryBuffer and 1 less malloc for every
MemoryBuffer pointing to a memory range translate into 20% less mallocs on
clang -cc1 -Eonly Cocoa_h.m.

This fixes PR7479 and PR7485. The test cases from those PRs are big, so not
included. However, PR7485 comes from self hosting on FreeBSD, so we will surely
hear about any regression.

10707f3b44 It's possible that a flag is added to the SDNode that points back to the

e5ff9ef195 Disallow matching "i" constraint to symbol addresses when 
address requires a register or secondary load to compute
(most PIC modes).  This improves "g" constraint handling.  8015842.

The test from 2007 is attempting to test the fix for PR1761,
but since -relocation-model=static doesn't work on Darwin
x86-64, it was not testing what it was supposed to be testing
and was passing erroneously.  Fixed to use Linux x86-64.

a24986d8bf Replace a big gob of old coalescer logic with the new CoalescerPair class. 
CoalescerPair can determine if a copy can be coalesced, and which register gets
merged away. The old logic in SimpleRegisterCoalescing had evolved into
something a bit too convoluted.

This second attempt fixes some crashes that only occurred Linux.
