Benjamin Kramer f600dc2eed simplify-libcalls: fold strncmp(x, y, 1) -> memcmp(x, y, 1) ...

The memcmp will be optimized further and even the pathological case
'strstr(x, "x") == x' generates optimal code now.

Analysis

Check function pointer first, before comparing function names.

Archive

Eliminate some unnessary Path::exists() calls.

AsmParser

Eliminate the restriction that the array size in an alloca must be i32.

Bitcode

Speedup bitcode writer. Do not walk all values for all functions to emit function local metadata. In one testcase, probably worst case scenario, the 70x speed up is seen.

CodeGen

Make post-ra scheduling, anti-dep breaking, and register scavenger (conservatively) aware of predicated instructions. This enables ARM to move if-conversion before post-ra scheduler.
