0fd19f4a95 The routines defined in comparedf2 and comparesf2 are defined in libc 
for softfloat mips. No need to include them here.

0b972ac92e Support armv7 builds for userland 
Make armv7 as a new MACHINE_ARCH.

Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.

Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).

Add armv7 to the universe build.

2b12718be6 Follow-up to r323001: if the actually selected CPUTYPE is capable of 
SSE2 instructions, we can use them.

e1ca2b88e2 In compiler-rt, a few assembler implementations for i386 floating point 
conversion functions use SSE2 instructions, but these are not guarded by
#ifdef __SSE2__, and there is no implementation using general purpose
registers.  For these functions, use the generic C variants instead,
otherwise they will cause SIGILL on older processors.

04a91333db Include {u,}{div,mod}si3() on mips in libcompiler_rt. 
These builtins were listed in the mips-specific Symbol.map for libc but
were not implemented.  Compiling mips with recent clang requires these
symbols.

813b8a9e89 Add an implementation of __ffssi2() derived from __ffsdi2(). 
Newer versions of GCC include an __ffssi2() symbol in libgcc and the
compiler can emit calls to it in generated code.  This is true for at
least GCC 6.2 when compiling world for mips and mips64.

040b30497c libcompiler_rt: move file list to Makefile.inc for reuse elsewhere 
Also switch to the style used in the clang390-import branch to reduce
future conflicts.
