07186e7840 the .eh_frame sections we generate need to be writable (which 
is why they are datarel).  This should fix PR4724, and is fallout
from r78890.

2399e49802 Revert a few changes that were done in 78603. 
PIC16DebugInfo currently rely on NameStr of composite type descriptors to uniquely
identify debug info for two aggregate type decls with same name.
This implementation will change when we have MDNodes based debug info implemenatation in place

8f6660c417 Don't setCalleeSavedInfoValid() until spills are interted. 
In a naked function, the flag is never set and getPristineRegs() returns an
empty list. That means naked functions are able to clobber callee saved
registers, but that is the whole point of naked functions.

This fixes PR4716.

e093ae5810 Update LocalRewriter::DistanceMap when inserting stack loads. 
In the included test case, a stack load was not included in DistanceMap. That
caused TransferDeadness to ignore the instruction, leading to a scavenger
assert.

ee52642cd3 use XCore-specific section with xcore specific cp/dp flags to restore

d69323d37a On x86-64, for a varargs function, don't store the xmm registers to 
the register save area if %al is 0. This avoids touching xmm
regsiters when they aren't actually used.

3a0cde8c91 Allow targets to specify their choice of calling conventions per 
libcall. Take advantage of this in the ARM backend to rectify broken
choice of CC when hard float is in effect. PIC16 may want to see if
it could be of use in MakePIC16Libcall, which works unchanged.

b9d9ce9513 llvm-mc: When handling a .set, make sure to print subsequent references to the 
symbol as the symbol name itself, not the expression it was defined to. These
have different semantics due to the quirky .set behavior (which absolutizes an
expression that would otherwise be treated as a relocation).

e8ee71bbd8 Revert r78424. 
In order for the changes in r78424 to work properly, cast_retty<X,Y> should return an object instead of a reference, and it's not clear that this approach has real advantages.
